Somehow I set out to purchase an oscilloscope for amateur purposes. There wasn’t enough money for a good digital one, and he didn’t really need any bells and whistles. Therefore, it was decided to start to purchase an analog one, from the time of the Soviets. Found an advertisement and went to buy. The owner assured that he was in working order. An on-site test in his garage showed that the appliance was not working. It turned out he did not turn on for about two years. Of the visible, only the backlight of the scale worked. As a result, the owner dropped the price, and I took the device at a cheap price. Previously, I had not repaired oscilloscopes, but there was a hope that all repairs would be reduced to replacing electrolytes, since, according to the owner, the device was working before it lay in the garage.

Arriving home and plugging the device into a power outlet, a strong heating of the power transistors on the rear panel was discovered. I decided to first disassemble and replace all the electrolytes. Which he did.
Just in case, I changed transistors 1-T1, 1-T2, 1-T3, T4, T5. In the process, I also found a charred 1-R28 and the Brightness control. I cleaned all the contacts with a special spray and alcohol. After all manipulations osc. turned on, there is a reaction to touching the probe with a finger. Brightness, vertical position is not adjustable. Astigmatism and focus adjust, but I can’t set a beautiful point, the cross turns out and is 1 cell below the center. When a signal is applied from the calibrator to the input, it shows garbage.
The main voltages were measured on the test block. All were underestimated. The stabilizer works, keeps its 8V and is regulated by a trimmer. I tried to turn it on without load by disconnecting the 1-Sh3 block and removing the block from the tube. Voltage is also low. There is a beam in the center, but the brightness is not adjustable. I measured the frequency on the collectors 1-T1, 1-T2 with a multimeter - about 1.7 kHz (according to the book it should be 2 kHz + -300 Hz). When working with connected and disconnected pads, transistors 1-T1, 1-T2 and res. 1R-27 get very hot.

Burnt resistor 1R-27 and a hot transistor.

Then soldered the resistor 1R-27. Enabled. The beam lit up brighter than before and ran across the screen Reacted to the handles (except for brightness). After a minute, everything went dark. The voltages on 1-Sh3 have dropped to 1-10V and are jumping. On the stabilizer, it also fell somewhere to 4-6V. Measured and with the CRT panel removed and dressed.

Subsequent manipulations revealed that the D2 diode on the 80V power supply burned out again. Restored. Turned on with the CRT panel removed and soldered 1R-27. Everything else is connected. All voltages on 1-Sh3 are normal. The transistors are warm, as they should be. I solder 1R-27 on the removed CRT panel, the voltages sag almost 2 times. When I turn it on with a CRT panel on with a soldered 1R-27, crackling is heard in the tube, and then diode D2 flies out again.

From everything, it became clear that the filament winding of the 1-Tr1 transformer was shorting to some of the secondary circuits. It was decided to power the glow separately by unsoldering the wires from 1-Tr1 and applying 6.3V to them from a separate transformer. When applying separate power to the glow, the oscilloscope worked as expected. Brightness control appeared after replacing the capacitor 1-C13. It also turned out to be broken. The transformer was built into the case of the oscilloscope, which now serves me safely in my home laboratory.

Design The oscilloscope is a desktop-based instrument made in a unified small-sized case. If necessary, the desktop version of the device can be built into a standard rack. To do this, the device can be supplied with an additional set of fittings, which allows you to install it in a typical rack with little time. Rack-mounted frame dimensions: width - 520 mm; height - 160 mm; p u b and n a - 480 mm. The frame in which the device is made consists of two supporting cast frames (front and rear) interconnected by two ties. At the junction of the front frame and the ties, scarves are installed that give additional rigidity to the connection. th thermal regime and ensuring natural ventilation, perforated holes are provided in the covers. On the bottom cover there are 4 support legs-shock absorbers. To install the device when moving in a vertical position, 4 legs-stands are provided, the height of which is chosen so as not to damage the external installation elements located on the rear panel. The device has a U-shaped transfer handle, which is attached to the side ties. When working with the device, the transfer handle serves as a stand that allows you to install the device in a fixed tilted position (7 positions) relative to the operator. For ease of installation and assembly, the device is structurally divided by the middle wall into two parts: functional block and power supply. The main functional block is placed in front of the device. To give the device rigidity, the middle wall is connected to the front panel using a longitudinal bracket. Attached to this bracket are the attenuator, sweep switch, and oversized sweep switch capacitors. The printed circuit boards of the "Y" amplifier, sweeps and synchronization are attached to the screeds and the middle wall with (using brackets and squares). Large-sized capacitors and a connector are installed on the middle wall, with which the power supply is connected to the functional unit. On the front panel of the device there is an ELT scale with a frame, all controls that are equipped with appropriate knobs and inscriptions (symbols). The cathode ray tube (ELT) is located in the upper left corner of the device. It is enclosed in a permalloy valve, which is attached to the frame and with a clamp - to the power supply unit.ELT is equipped with a system for combining the scanning line with the scale and scale illumination.The power supply unit is located at the rear of the device.All the main elements of the power supply unit are placed on a vertical and horizontal chassis, which are attached to the rear frame and side braces.On the horizontal chassis are installed: power transformer, high-voltage rectifier and output voltage filter board. The high-voltage rectifier is provided with a cover with a warning label. The remaining elements of the power supply are located on the pallet directly or with the help of special brackets. On back panel output: -power connector, supply voltage switch. 15 fuses, "Z" socket, earth clamp, viewing window of the hour meter. On the right tank wall there are: sockets and switch "PLATES X", "ON", potentiometers "CALIBRATION OF DURATION", socket "C-IV", socket "ę-: A" switch "-, P". earth clamp. On the left side wall are: sockets and switch "PLATES Y", "ON". All elements under high voltage(more than 250 V), equipped with protective covers and warning labels. The electrical installation was carried out printed circuit boards except for large items. The design of the device ensures its ease of use. 5. 2. Principle of operation The block diagram of the oscilloscope (Fig. 1) consists of the following main components: .input attenuator: input stage of the beam vertical deflection amplifier; the preliminary stage of the vertical deflection amplifier of the beam; the final stage of the vertical deflection amplifier of the beam; amplitude and time calibrator, synchronization circuit; sweep control trigger; sawtooth voltage generator; launch blocking circuits; schemes for the formation of blanking pulses; output sweep amplifier; power node; cathode ray tube (E L T) . The investigated signal is fed to the socket "1MQ50 pp". With the help of an input attenuator, which "is a compensated voltage divider, a signal value is selected that is convenient for observation and research on the CRT screen. The beam vertical deflection amplifier amplifies the signal to the required value before it enters the vertical deflection of the plate. To trigger and synchronize the sweep, the signal under study can be used, amplified by the vertical deflection amplifier of the beam - with internal I. Structural analysis of the instrument. its synchronization, or an external signal applied “a njezd (synchronization input“ ” - with external synchronization. The synchronization and triggering circuit generates a sweep rectangular pulses constant amplitude, regardless of the size and shape (of the incoming signal. This ensures a stable start-up of the sweep generator that generates a sawtooth voltage. The sawtooth voltage is amplified to the required value by the horizontal deflection amplifier and fed to the CRT tilting plates. The device provides for the possibility of an external signal being fed to the sweep amplifier when it is applied (to the "X" socket, while the sweep amplifier is disconnected from the generator circuit. The CRT beam brightness control circuit generates rectangular pulses that enter special blanking plates and extinguish the ELT beam during the reverse sweep.The calibrator generates rectangular pulses that are used to calibrate the gain of the vertical deflection amplifier and to calibrate the sweep duration.The oscilloscope provides for obtaining brightness marks when an external signal is applied to the “Z” socket. The power supply unit provides the entire instrument circuit with supply voltages. 5. 2. 1. The input attenuator is a frequency-compensated voltage divider (Fig. 2). The divider has 12 division steps with division ratios of 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000, 2000, 5000. Precision resistors are used in the input attenuator and the resistance values ​​are selected in such a way that the same input resistance is provided regardless of the position of the voltage divider "V / cm, mV / cm ". Variable capacitors C3, C4, C13, C14, C22 at the input of each attenuator circuit allow you to adjust the input capacitance so that it has the same value for (all positions of the attenuator. Variable capacitors C5, C6, C15, C16, C23 allow you to compensate the attenuator over the entire frequency band. The input attenuator is structurally made in the liquid of a separate node on switch B1. When using a remote divider 1: 10, the total division ratio increases by a factor of 10. 18 2 "19 From the output of the attenuator, the input signal enters the input stage of the vertical deflection amplifier. symmetrical scheme with pair-matched transistors T2, T3 for the minimum spread of drain current. Resistor R4 and diodes D1 ... D4 protect the field trap resistor T2 from overloads from the input side. Transistor T1 acts as a current stabilizer. To equalize the currents in the arms of transistors T2, T3, the RIO potentiometer is used. Additional balancing is carried out using the potentiometer 1-R7 ("BALANC"), Switch 1-B5 serves to reduce the sensitivity by 10 times. Capacitor C2 serves to equalize the input capacitance when switching the toggle switch 1-B5. Then the signal goes to the bases of the first pair of transistors of the microcircuit M c i , which are used as emitter followers. 5. 2. 3. Preliminary amplification stage (Fig. 4) From the output of emitter followers, the signal is fed to a divider consisting of resistors R23, R26, R29, R30, R31. On the divider, the amplifier gain is halved using the B1-5 switch and resistors R27, R28, the gain is smoothly changed using the RI4 (U1-2) resistor, and the gain is calibrated using the resistor 1-R9 (""). With the help of resistor R30, the amplifier is balanced when its gain changes. Further, the signal is fed to the bases of the second flock of transistors of the transistor assembly M c i, which are included as a balanced amplifier, from the output of which, through resistors R36, R37, it is fed to the pre-output amplifier assembled on the MS2 chip. The vertical movement of the beam is carried out by the potentiometer 1-R10 (" | "). Potentiometer R40 serves to center the beam at the middle position of potentiometer 1-R10 ("|"). From the output of the pre-output amplifier, the signal is fed to the input of the emitter followers of the cascade. Emitter followers are made on transistors T4, T5 type 2T301D. 20 T5 5. 2. 4. End stage of the vertical beam deflection amplifier (Fig. 5) »80b From the output of the output stage, the signal is fed to the vertical deflection plates of the CRT. At the same time, the signal from the collector of transistor T1 through the emitter Follower (TK) is fed to the synchronization circuit. To correct the frequency response, current feedback is used (C l, R l, R2). The frequency of the calibrator (2 kHz ± 2%) is determined by the circuit 23 CVI. 6. Calibrator I,i.I C 1 included in the collector circuit of the transistor TK. The resulting pulse on the resistor R4 with a frequency of 2 kHz is fed to the emitter follower (T 1), from the load of which the voltage calibrated in amplitude and frequency is removed.

Схема синхронизации (рис. 7) Схема синхронизации (плата У 4) обеспечивает синхронную работу генератора развертки с исследуемыми сигналами, что дает.возможность наблюдать на экране Э Л Т устойчивое изображение. Схема синхронизации состоит из селектора синхронизации, усилителя синхронизации и триггера синхронизации. Сигнал синхронизации в зависимости от.выбранного источника синхронизации подается или с усилителя вертикального отклонения.пуча, или с гнезда I Тн1 (« -£) ») (внешняя синхронизация) . При запуске от внешнего источника сигнал синхронизации, в зависимости от величины, поступает на базу эмиттер-ного повторителя (T I) непосредственно или через делитель (резисторы 1-R1, 1-R2, 1-R3). Усилитель синхронизации состоит из двух каскадов, которые в зависимости от положения переключателя синхронизации (I-ВЗ) работают следующим образом. При запуске положительным сигналом база триода усилителя (ТЗ) подключается к выходу входного эмиттерного повторителя, а база эмиттерного повторителя (Т2) подключается к потенциометру I R6 (« У Р О В Е Н Ь ») , Усиленный сигнал, снимаемый с коллекторной нагрузки R1I (плата У4), будет иметь полярность, противоположную входному сигналу. При выборе запуска от отрицательного сигнала база транзистора (Т2) усилителя подключается к выходу входного эмиттерного повторителя, а база транзистора ТЗ - потенциометру I R6 (« У Р О В Е Н Ь ») , При этом сигнал синхронизации проходит два эмиттерных повторителя и подается на эмиттер усилшсля (ТЗ). В этом случае усилитель работает по схеме с общей базой и amplified signal trigger, taken from the collector load of the amplifier, will be of the same polarity as the input signal. Potentiometer 1-R6 (“LEVEL”) selects the trigger level of the sync trigger, which makes it possible to change the start of the sweep trigger. J5 gob For the formation of synchronization pulses, a Schmitt trigger was used, assembled on the first pair of transistors of the transistor assembly M c i . In the initial state, the first transistor of the transistor assembly is open, and the second is closed. The synchronization pulses generated by the trigger, the repetition rate of which corresponds to the frequency of the synchronization signal, are differentiated (capacitor C7) and fed to the start of the sweep control trigger. 5. 2. 7. Sweep control trigger (Fig. 8) The trigger is assembled on the second pair of transistors of the transistor assembly M c i . Before the trigger pulse arrives, the first trigger transistor is open, and the second is closed. Negative sync pulses generated by the sync flip-flop enter the base of the first flip-flop transistor and trip the flip-flop. In this case, the switching diodes D5, D6 are blocked and the sweep generator begins to form a sawtooth voltage. Upon reaching a predetermined level, the sawtooth voltage, removed from the load part R49 of the emitter follower T8, through the blocking circuit (emitter follower T6) affects the base of the first trigger transistor and overturns the trigger to its original state. Potentiometer I R8 "STABILITY" you can change the position of the operating point of the first assembly transistor and thereby transfer the sweep generator to self-oscillating or Standby mode. From the load of the first trigger transistor through the emitter follower (T4), a signal is supplied to the beam brightness control circuit ELT. C) In the initial state, the key, consisting of diodes D5, D6, is open and, therefore, the time-setting capacitor is shunted. With the arrival of a negative pulse on the key, the latter closes, which corresponds to the forward sweep. 27 During the forward stroke of the sweep, the time setting capacitor C z g is charged, through the corresponding time setting resistor from the source minus 20 V, which (causes a decrease in the potential at the gate of the transistor T5. The source follower T5 increases the input resistance of the generator, which makes it possible for the time setting elements to use large resistors with a relatively small value of the capacitance of the capacitors, while obtaining the corresponding duration (Sawtooth leg voltage. A decrease in the base potential of the TT triode causes an increase in the potential of its collector, which, through a time-setting capacitor, is transmitted to the gate of the TG source follower. feedback . Due to the high gain of the T7 amplifier stage and the deep negative feedback, the driver capacitor charges at a constant rate. The process of charging the timing capacitor creates a sweep stroke. Kremyazadyaschis capacitors ai resistors are selected using the switch I-B6 ("V R E M I / S M"), Potentiometer 1-R17 is used to smoothly change the sweep speed during operation of the device. In the right extreme position, the 1-R17 potentiometer has a mechanical fixation, and the sweep duration has a calibrated value. 5. 2, 9. Sweep reverse blocking circuit (Fig. 8) The circuit performs two functions: - transfers the sawtooth voltage from the generator output to the control trigger, which, upon reaching a predetermined level, overturns the trigger "into a state corresponding to the formation of the sweep reverse: - during the reverse sweep, the sweep maintains the voltage at the base of the first trigger transistor at such a level that the pulses coming from the synchronization trigger cannot overturn the sweep trigger. The blocking circuit consists of an emitter a repeater on a transistor T6 of type 2T301D, the load of which is a resistor R40, shunted by capacitors Sol (I-C6, 1-C7, 1-C8, C14, CIS, C16). so as to ensure during sweep retrace and time 28 Stability1 FIG. 8.

The ELT beam control circuit (Fig. 10) generates pulses intended for beam switching during the forward and reverse stroke. It includes an amplifier on the transistor T1 "and an electronic switch on the transistor T2. The circuit is controlled by pulses coming from the sweep control trigger. On the blanking plates CHO When the collector voltage T l drops to + 2 0 V, the diode D 2 opens and fixes it at this level. The potentials of the plates are equal, and the beam illuminates the ELT screen. At the end of the forward sweep stroke, the transistor (T I) is locked, the plate potential increases, and l h deviates outside the screen. The circuit provides for the possibility of modulating the beam brightness (by an external signal.

Further operations are carried out using the sweep and synchronization modes listed below, as indicated in paragraphs 8.1. and 8.2. 8. 4. Sweep from an external source and the LEVEL knob - to one of the extreme positions. Set the duration switch and the sweep multiplier toggle switch to the desired position if the approximate duration of the process under study is known. Set the "V/cm, mV/cm*" switch to the position at which the value of the signal under study on the device screen is most convenient for observation. Connect the signal under test to the "-£) 1MJ50 pF" socket. Turn the "STABILITY" knob to the right until the image appears on the CRT screen. Rotate the same knob in the opposite direction, set it to the position where the sweep breaks. This position corresponds to standby mode. Turn the "LEVEL" knob until a stable signal image appears. The synchronization polarity selection switch (“- , + , ~ , ~ ”) can start the sweep from the positive or negative part of the signal by setting it to the “- (-” or “-” position. " so that on the screen - Set the knob (switch "X, xl, x0.2" to position "X". Apply a sweeping voltage from an external source to the socket "" in X. Use this mode of operation in cases where horizontal deflection of the beam requires not a sawtooth voltage, but a signal of a different shape, for example, sinusoidal. 8. 5. External modulation of the beam in brightness 8. 6. Applying the voltages under study to the plates of the CRT directly. S Y ”and“ PLATES X ”are under a potential of about + 5 0 V. Set the toggle switch for switching plates to the position “V K L.”. The entrance to the plate is symmetrical. One of the plates can only be grounded through an external capacitor. x Moving the image can be done by "-*-" and "t". handles When external voltage is applied to the plates X, the switch “X, x l, x0.2” should be set to the “X” position. It is possible to measure time intervals using luminance marks with a known frequency or repetition period. For beam modulation, a sinusoidal or pulsed voltage is used. 8. 7. Measurement of time intervals Obtain a clear still image on the CRT screen. To ensure maximum measurement accuracy, use the baseband external sweep synchronization mode. Adjust the handles "BRIGHTNESS" and "F O observe the following measurement conditions: CUS" the image so that on the oscilloscope screen there are - the size of the image of the measured time interval! should be large, which reduces the reading error pr; we see clear bright marks with dark intervals between them. The duration of the time interval is determined by multiplying the measurement; by changing the number of marks that fit into its image, the horizontal dimensions of the images of the measured and ka for a known repetition period of the modulating signal. The calibration signals (or several of their periods) should be as similar as possible, which eliminates errors due to horizontal nonlinearity, because in this case, action 8. 8. Measurement of the frequency outside the non-linearity is the same for the measured and calibrated signal; The frequency of the signal can be determined by measuring its period T, - calibration before measurement must be carried out for each of the positions of the multiplier "x1-x0.2"; - to reduce the measurement error due to the thickness of the beam line, measurement and calibration should be performed either on the right or both on the left edges of the image; "- measurement and calibration should be carried out on the axial line of the scale with divisions. to horizontal! Before measuring, set the knob "DURATION" to the extreme right position. In this position, the sweep is calibrated and corresponds to the graduation of the “TIME/CM” switch. Check the calibration of the sweep duration using the internal calibrator in accordance with subsection 7.2. Set the measured time interval in the center of the screen with the knob “<-> -". Set the “TIME / C M” switch and the “X - x l - x 0, 2” switch to such a position that the measured interval occupies a length on the screen - at least 30 mm of the scale. The measured time interval is determined by the length of the measured time interval on the screen horizontally in divisions of the scale (see), the value of the sweep coefficient (digital mark. of the duration switch "Pa., sweep) and the value of the sweep multiplier (xl-x0.2"). If, when measuring periodic signals of short duration, the duration of several of its periods is measured, then the duration of one period is determined by the additional division of the specified product by the number of measured periods. Count the distance in divisions of an integer number of signal periods that fit closest to 8 divisions of the scale. Let, for example, 8 periods occupy a distance of 4 divisions for a duration (sweep factor) of 5 microseconds/cm. Then the desired signal frequency is f = f = 4-I-10 " = 0.4-106 Hz. (2) where n is the number of periods; I is the distance in scale divisions occupied by the measured area; t p is the sweep duration (sweep coefficient). Another method for determining the frequency is the method of comparing the unknown frequency with the reference one according to the Lissa zhu figures. In this case, the vertical deflection amplifier (input "r) l M 8 5 0 p F ") and emit a signal whose frequency must be measured, and the horizontal deviation amplifier (input * X") - the signal of the reference frequency generator. When the frequencies approach, a rotating ellipse is sent on the screen, the stop of which indicates "a complete coincidence of frequencies. With a multiple ratio of frequencies on the screen, a more complex figure is obtained, and the frequency along the vertical is related to the frequency along the horizontal in the same way as the number of points of contact of the tangent to the figure along the horizontal is related to the number of points of contact of the figure to the tangent along the vertical. It is also possible to determine the division of frequency with the help of brightness marks obtained by i j the supply of the reference frequency, a multiple of the studied sig; crowbar, on the nest "Z". tions, OSCILLOSCOPE pzhy S AND ". 9 1. Operations and means of verification verification operations and 8. 9. Measurement of the amplitude of the studied signals To ensure maximum measurement accuracy, it is recommended to observe the following conditions during measurement: 3. - the range of the image of the measured signal should be large, which reduces the reading error of the measurement; - the range of images of the measured and calibration annals should be the same (possible non-point number equality - up to 1.5 s m), which allows minimizing but still the error due to vertical non-linearity, i.e. to. its effect of TO in this case is the same on the measured and calibration signals; calibrate the deviation coefficient separately for each of the positions of the multiplier « x lI - xvlfW. 10"; Table 3 at - 9. 3. 1 9. 3. 2 - measure the amplitude on the vertical axial line of the scale or in the place where the calibration was carried out 9. 3. 3, which makes it possible to eliminate the error due to geometric * distortions, which are most manifested at the smallest image span at the edges of the working "" area of ​​the screen; - measurement in calibration should be carried out taking into account the thickness of the beam line. Before measurement, check the calibration of the deviation coefficient of the vertical beam deflection amplifier in accordance with subsection 7-2, in the position of the “x10, xl” toggle switch in which the amplitude is measured. Apply to the socket up to "-E) l M Q 5 0 p F" the signal under study. The “STRENGTHENING” handle must be in the extreme position. Set the “V/cm, mV/cm” switch to the image size within the working part of the screen, “about at least 2 cm.

A sinusoidal voltage with a frequency of 1 kHz is supplied to the input of the oscilloscope under test from the G4-117 generator so that the size of the image on the device screen is 4 div. (40 m m) vertically. The image size is checked at frequencies of 0.10, 100 Hz; 1, 50, 200, 500 kHz; 1 MHz. The voltage at the amplifier input of the tested oscilloscope is maintained constant and monitored in the frequency range from 50 Hz to 200 kHz using a BS-38 voltmeter, and in the frequency range from 200 kHz to 1 MHz - using a B3-39 (VZ-14) voltmeter. In this case, but the B3-39 voltmeter maintains the voltage value, which was fixed at a frequency of 200 kHz. The unevenness of the amplitude-frequency characteristic at frequencies from 100 Hz and below is checked using the GZ-47 generator. In this case, the voltage of the GZ-47 is set according to its internal voltmeter according to the height of the oscillogram received from the G4-117 generator at a frequency of 100 Hz, and then it is maintained constant by the internal voltmeter of the GZ-47 generator within the frequency range corresponding to a certain position of the frequency multiplier on the GZ-47.
