Oscilloscope C1 101 Power supply diagram. How to achieve a steady image signal

Bought oscilloscope C1-94 somehow for repairs (has long thought about the purchase of such an appliance), he is not new and got cheap, the truth is probe there it turned out to be homemade, then he alleged him, but still, since the device was rarely used - I decided to replace it a bit and replace it, What did not work and gave the shoals. So, I found a scheme, I studied a bunch of forum, manuals and several articles. All this took a few days for 3-4 hours a day! There was a lot of information to explore - this is still not a coffee maker, but a complex measuring device - some newbies also try to repair, but they rush at him immediately with the soldering iron and in a couple of hours I do not solve the problem here, you need to approach, knowledge, experience.

Scheme principled C1-94

In general, for a start, I will tell you briefly about the oscilloscope and its features, pros and minuses, and in general, in general. There may be a lot of letters here and a lot, but I think this category.

So, the main plus of this measuring device is that there is no chip and assemblies in it. Repairing looking for a rare replacement here is almost nothing, repair transistor scheme With some of the sides even better.

Of course there are several rare elements - such as in the generator germany transistors And other trifles-scatter, but it is usually high quality and breaking can rarely.

The oscilloscope is closed with a casing - to remove which you can unscrew 4 screws and removing the legs with the stands, remove the casing, on the frame the main board where almost all of the power supply unit and other regulating elements are mounted.

There is also a folding fee that is done for the convenience of mounting and repair, and the board is closed with a plastic cover from behind, which is fastened with a screw - and unscrew which just wry!

The tube for the convenience of repair took off - to unscrew the clamp slightly shock it, as well as the lock guide, which bleaks fixed to adjust the position of the tube.

It is better to mark the panel with the marker since there is no key on it and then you can measure the heat for a long time to put in the desired, correct position. The wires are flexible, durable, I did not break anything in the process of repair, everything was done on conscience - these are not modern gentle Chinese devices, where half the wiring and part of their fasteners may fall off. In particular, there was a bad voltage balancing of 12-0-12 volts (two-polar), there is a miser, and I didn't regulate about 1 volt, I did not regulate.

The electrolyte began to check, simply falling out in turn and measuring the container for those that could reach - the couple turned out to be a snack, one new blew himself, confusing the polarity of the reverse sprocket - on the board a completely scant marking on the textolite, and if you get a lot of elements, you can get lost when installing several items. .

When the voltage was able to set up the norm - the balance was the one that was needed, set up the scan controllers, adjusted all the parameters, performed calibration as it should be supplied, filed a signal from the generator assembled on a popular chip NE555, looked - everything is in order, the device is now what it is necessary.

By the way, the dust also need to wipe the dust - and the napkin is not better wetted in water, but to take something ready, impregnated with alcohol or other similar means in order to prevent oxidation of parts and elements of the schemes.

Switches can be cleaned, and their contacts with acetone wipe, so that they are glistened, and not black. Then, when switching, the operation modes of the device will not be jumps and serious distortions.

When reverse assembly, after repair, check the position of the tube and put it smoothly. The article makes all the schemes and materials that helped me in the repair of this wonderful service oscilloscope. Repairs executed Redmoon.

Model oscilloscope C1 73 - the most common domestic device for monitoring the form of electrical signals and measure them technical parameters In its class (electron beam). It has a lot of advantages: acceptable price, simple designSmall dimensions and good performance properties. It is these advantages of the signal meter that made it popular among technical specialists and radio amateurs.

Purpose and general information

The C1 73 brand oscilloscope is intended for research procedures over electrical signals that have the following characteristics:

frequency range - from 0 to 5 MHz;
amplitude - from 20 mV to 120 V (if there is a remote divider 1:10 in the configuration, the range of measured amplitude increases to 350 V);
the ability to measure the electrical barrier of both constant and alternating type;
the range of time intervals is from 0.4 μs to 0.5 s.

Nutrition oscilloscope C1 73 occurs from the network with a voltage of 220 V (the delivery set includes a rectifier) \u200b\u200band from permanent source Electric slippers 27 V. From the source of permanent electrotock, the device consumes about 19 W, and 30 W range from the network of AC power. The mass of the device is 3.2 kg and 4.5 kg with auxiliary rectifier. The display is the oscillographic electron beam tube, has dimensions of 6x4 cm (SHX).

Important! Information on the rules of use can always be found in the operating instructions or free access on the Internet.

Criterias of choice

The choice of oscilloscope is a difficult task that requires a thorough approach, since each device differs from each other by many parameters and properties.

When choosing a meter under consideration, you should pay attention to the following points:

Type of measuring electrical appliance - are analog and digital. Analog oscilloscopes are distinguished from digital variants by processing the incoming signal. Digital meters more perfect and powerful, but they have a high cost and often difficult management;
Installation method - are portable, or portable, stationary and with USB interface (Convenient for car enthusiasts);
The bandwidth is the main characteristic of the meter. It is it that determines the range of measured electrical signals. Choosing the product according to this parameter, it is necessary to proceed from the characteristics of the measurement object signals;
Discretization frequency (sampling frequency) - provides a real-time transmission band for each channel;
Depth of memory. The higher this indicator, the more difficult the signals will be able to obtain an electrical appliance;
The number of channels - this parameter is wenst on how many channels can be observed at a time;
Oscillogram update rate. The greater this indicator, the higher the probability to catch rare and random events, which is important for proper debugging projects.

Specifications of popular domestic oscilloscopes

On a note. Oscilloscope H3013 is demonstration and used usually by teachers educational institutions in laboratory classes. Find on sale such an instance in working condition is extremely difficult.

Check, set up and adjust the device

Any measuring device, including the oscilloscope, needs to be regularly verified, since with the time setting the instrument can be shot down, or some radio elements fail, which leads to an incorrect measurement of parameters.

After any repair, and better on an annual basis, it is necessary to check and adjust the electrical component of the meter. These procedures can be performed in specialized centers or independently. However, to independently check the parameters of the product will require certain knowledge and the presence of the following equipment:

voltmeter working with high resistance;
oscilloscope model C1 101 or C1-68 and the like;
kilovoltmeter;
ampervoltmeter;
frequency meter with an upper limit of at least 1 MHz;
pulse signal generator.

Important! If the oscilloscope is applied in research activities or a supervisory organization, then it must take a calibration on an annual basis in specialized bodies, which give a special dated permission to use.

The oscillographic device is an indispensable device in electrical engineering, which allows the monitoring of electrical waves. There is also no repair workshop without this meter, a scientific and technical laboratory. It is necessary to approach the oscilloscope choices carefully so that the measurement result is correct and satisfy the existing need.

Briefly was talking about it universal device. The above information is enough to make the measurement process conscious, but in the case of repair, such a complex device will need deeper knowledge, because the circuitry of the electronic oscilloscopes is very diverse and quite complex.

Most often, a union oscilloscope is at the disposal of a novice radio amateur, but having mastered the techniques to use such an instrument, will not work to go to a two-beam or digital oscilloscope.

Figure 1 shows a fairly simple and reliable oscilloscope C1-101, having such a small number of handles that it is absolutely impossible to get confused. Please note that this is not some oscilloscope for school lessons of physics, it was this that was used in production only twenty years ago.

The nutrition of the oscilloscope is not only 220V. Possible powered from the source direct current 12V, for example car batteryThat allows you to use the device in the field.

Figure 1. Oscilloscope C1-101

Auxiliary adjustments

On the top of the oscilloscope panel there are knobs of adjusting the brightness and focusing of the beam. Their appointment is understandable without explanation. All other controls are located on the front panel.

Two knobs designated by arrows allow you to adjust the position of the beam vertically and horizontally. This allows you to more accurately combine the image of the signal on the screen with the coordinate grid to improve the sections.

The zero voltage level is on the central line of the vertical scale, which allows to observe a two-blood signal without constant component.

To study a unipolar signal, for example digital circuits, the beam is better to move to the lower division of the scale: one vertical scale of six divisions will be obtained.

The front panel also contains the power toggle switch and the inclusion indicator.

Strengthening the signal

The "V / Aff" switch sets the sensitivity of the channel of the vertical deviation. The enhancement of the channel Y is calibrated, changes in increments 1, 2, 5, there is no smooth adjustment of sensitivity.

The rotation of this switch should be achieved so that the switches of the pulse under study were at least 1 division of the vertical scale. Only then can be achieved sustainable signal synchronization. In general, it should be striving, to get the scope of the signal if possible, until it went beyond the coordinate grid. In this case, the accuracy of measurements increases.

In general, recommendation for the gain of the gain may be like this: unscrew the switch counterclockwise to the position of 5V / cases, then rotate the handle clockwise until the scope of the signal on the screen is as recommended in the previous paragraph. It is like: if the value of the measured voltage is unknown to start measurements from the highestoscience itself.

The most recent clockwise position of the vertical sensitivity switch is indicated by a black triangle with the inscription "5". In this position on the screen there are rectangular pulses by scope of 5 divisions, the frequency of 1 kHz pulses. Purpose of these pulses - check and calibration of the oscilloscope. Due to these pulses, a somewhat comic case is remembered, which can be told as a joke.

Somehow came to us in a workshop one comrade and asked to use the oscilloscope to establish some kind of self-configuration. After several days of creative torment, he heard from him such an exclusion: "Oh, you, and the power turned off, and what the impulses are good!". It turned out that by ignorance, he simply turned on the calibration pulses, which are not controlled by any handles on the front panel.

Open and closed entrance

Directly under the sensitivity switch is a three-position switch of operating modes, which are often called "open entry" and "closed". In the extreme left position of this switch it is possible to measure direct and alternating voltages with a constant component.

In the right position, the entry of the vertical deviation amplifier is turned on through a condenser that does not miss a constant component, but you can see the variable, even if the constant component is far from 0.

As an example of using a closed entry, you can bring such a common practical task as the measurement of the pulsations of the power supply: the output voltage of the 24V source, and the ripples should not exceed 0.25V.

If we assume that the voltage is 24V during the sensitivity of the vertical deviation channel 5V / cases. It will take almost five divisions of the scale (zero will have to be installed on the lowest line of the vertical scale), the ray takes off for the very top, and pulsations in the tenths of the volt will be almost invisible.

To accurately measure these ripples, it is enough to translate the oscilloscope into the closed entry mode, place the beam in the center of the vertical scale and choose a sensitivity of 0.05 or 0.1V / cases. In this mode, the pulsations will be quite accurate. It should be noted that the constant component can be large enough: the closed entrance is designed to work with constant tension up to 300V.

In the middle position of the switch, the measuring probe is simply turned off from the input of the Y amplifier, which makes it possible to set the position of the beam without turning off the dipstick from the signal source.

In some situations, this property is quite useful. The most interesting thing is that this position is marked in the oscilloscope panel of the general wire icon, the Earth. It seems that the measuring probe is connected to the shared wire. And what will happen then?

In some oscilloscopes models, the input mode switch does not have a third position, it is just a button or toggle switch, switching outdoor / closed modes. It is important that in any case there is such a switch.

To preliminarily evaluate the performance of the oscilloscope, it is enough to touch the signal with the finger (sometimes they say hot) the end of the measuring probe: a network tip in the form of a blurred beam should appear on the screen. If the sweep frequency is close to the frequency of the network, a blurred, torn and shaggy sinusoid will appear. When touching the finger of the "earth" end of the tip on the screen, naturally, will not be.

Here you can remember one of the ways to check capacitors for a break: if you take a good capacitor in your hand and touch it with a hot-end, then the same shaggy sinusoid will appear on the screen. If the condenser is in the cliff, then no changes on the screen will occur.

Switch "Time / Del." Installed sweep duration. When observing a periodic signal, the rotation of this switch should be achieved so that one or two signal periods should be displayed on the screen.

Figure 2.

The synchronization knob of the Oscilloscope Oscilloscope C1-101 is indicated by just one word "level". At oscilloscope C1-73 in addition to this handle there is a stability handle (some feature of the scanning scheme), some oscilloscopes are called simply "Synch". You should tell a little more about using this handle.

How to achieve a steady image signal

When connected to the circuit under study, the picture, shown in Figure 3, may appear on the screen.

Figure 3.

In order to get a stable image, you should twist the "Synchronization" knob, which on the front panel of the oscilloscope C1-101 is indicated as "level". For some reason, different designations of the governing bodies for some reason are found on different oscilloscopes, but in essence it is the same handle.

Figure 4. Image Synchronization

To get a steady signal from the blurred image shown in Figure 19 to get a steady signal "Synch." or in our case "level". When rotating counterclockwise before the "minus" sign, the signal appears on the screen, in this case the sinusoids shown in Figure 20A. Synchronization begins on the incident signal front.

When rotating the same handle to the "plus" sign, the same sinusoid will be viewed as in Figure 4B: the sweep is started along the ascending front. The first period of sinusoids begins slightly above the zero line, it affects the start time of the sweep.

If the oscilloscope has a delay line, then there will be no such disappearance. For sinusoids, it may not be particularly noticeable, but when studying a rectangular pulse can be lost in the image of the entire front of the pulse, which in some cases it is quite important. Especially when working with external scan.

Work with external scan

Next to the regulator "Level" is a toggle switch marked as "external / ext". In the "Internal" position, the sweep is started from the test signal. Enough on the Y input to submit the signal under study and twist the "Level" knob as a stable image appears on the screen, as shown in Figure 4.

If the mentioned toggle switch is to "External" position, then get a stable image will not be able to rotate the "Level" knob. To do this, you need to send a signal to which the image on the external synchronization input will be synchronized. This input is located on a white plastic panel located on the right of Y.

In the same place the sweep voltage exit jacks are located (used to control various GKCH), the output of the calibration voltage (can be used as a pulse generator) and the socket of a common wire.

As an example, where it may be necessary to work with an external scanning can serve as a pulse delay circuit shown in Figure 5.

Figure 5. Pulse delay scheme on timer 555

When a positive pulse is applied to the input, the output pulse appears with a delay determined by the RC parameters of the chain, the delay time is determined by the formula shown in the figure. But according to the formula, the value is determined quite approximately.

If there is a two-beam oscilloscope, it is very simple to determine the time: there are enough of both signals for different inputs and measure the pulse delay time. And if there is no two-beam oscilloscope in the presence? This is where the external sweep mode will come to the rescue.

The first thing to do is to submit an input signal of the circuit (Fig. 5) to the input of external synchronization and here to connect the Y input. Then rotating the "level" knob to achieve a stable image of the input pulse, as shown in Figure 5b. At the same time, two conditions must be observed: the "Extra / Ext" toggle switch is set to the "External" position, and the test signal D.B. Periodic, and not one-time, as shown in Fig. 5.

After that, you need to remember the position on the input screen and submit to the input y output. It remains only to calculate the required delay in dividing the scale. Naturally, this is not the only scheme where it may be necessary to determine the delay time between two impulses, such schemes a great set.

In the next article, it will be described about the types of signals under study and their parameters, as well as about how to conduct various measurements With the oscilloscope.
