However, this device does not allow analyzing the dependence of the output power of the process under study on the frequency. The purpose of the invention is to expand the field of application of the device by recording the dependence of the output power of the process under study on the frequency. The goal is achieved by the fact that a device containing electron beam

The drawing shows the functional diagram of the device.

The device contains a cathode ray tube 1 (CRT) with memory, control unit 2, readout signal sweep unit 3, readout signal illumination unit 4, second trigger 5, third element bb, time calibration unit 7 of the recorded process, trigger generator 8. element OR 9, first element AND 10, block 11 sweep of the recording signals, block 12 of the light of the recording signals, reversible counter 13 register 14, adder 15, second element AND 16, block 17 of delay, meter 18 of signal duration, digital-to-analog converter 19, trans s trigger 20, the pulse generator 21, the fourth AND gate 22, decoder 23, memory unit 24, read amplifier 25, a display unit 26.

The device works as follows.

Before registering the studied processes, a sweep is selected, the duration of which is equal to the sum n of the durations of the recorded signals (i.e. to fit n signals — on one raster), then the screen of the electron-beam tube 1 (CRT) is prepared for recording, carried out by command the control unit 2 for switching to the mode of preparing the source of pichan, launching scanners 3 and highlighting 4 read signals. At the same time, on a CRT screen, a television raster of the television type is displayed, after its control unit 2 transfers the power source to the recording mode, sends a command to the single input of the second trigger 5, sets the permission potential to the third element 6, sends the command to block 7 temporary the calibration of the recorded process and the driver of the 8 trigger pulses, which, through the elements AND 6, OR 9, AND 10, starts the sweepers 11 and the illumination of the recording signals 12, thereby reproducing the calibration sinusoid on the screen of the CRT 1, corresponding to shcha this range sweeps. In this case, the control unit 2 displaces the recording beam along the screen field, recording a sine wave in the lower part of the screen floor. Then, the second trigger 5 is repeatedly set to one and the trigger generator 8 and blocks 11 and 12 are started. The level of the recording beam is shifted above the recorded calibration sine wave (i.e. the zero line is recorded), after which the beam. is transferred to the zero line zero position, the 5x states of the trigger 5, the reversible counter 13, the register 14 are set and 5, and a code equivalent to the sweep duration is written to the adder 15. The device is in standby mode. With the arrival of the first signal under investigation, the driver of 8 trigger pulses is triggered, which, through elements AND 6, OR 9, AND 10, starts blocks 11 and 12 and sets the resolving potential to the second element AND 16, while on the screen of CRT 1 it is recorded on the I-th part of the scan The signal of the process under investigation, which falls on the stroke of the coaxial deflection system through the delay block 17, according to the response time of blocks 11 and 12.

At the same time, the signal under study is fed to the input of the meter 18 of the duration of the signals, where its duration is measured, after which the binary code equivalent to its duration is recorded from its output into the adder 15, where it is subtracted from the sweep duration code. From the output of the adder 15, the resulting code is written in the form of an inverse code into a reversible counter and register 15, and using a digital-to-analog converter 19, the recording beam is shifted along the time axis by the duration of the recorded signal.

With the arrival of the next signal under investigation, the driver of the trigger pulses 8 is activated and the trigger of the second element I 16 is given a start pulse, setting the first trigger 20 into a single state allowing the generator 21 pulses to pass through the fourth element 22 of the reversible counter 13. On receipt the zero code in the reversible counter 13 at the output of the decoder 23 a permitting potential is formed allowing the pulse of the Generator 21 to pass through the second element 16 to start the blocks 11 and 1 while on the screen of the CRT 1 On the fifth part of the sweep, the next signal of the process under investigation is recorded, which is fed to the input of the coaxial deflection system of the CRT 1. Then the whole process occurs similarly to the one described above. The calibration is performed before the entire sweep is filled with the fifth number of signals, according to which the analysis will be carried out. The device goes to the readout according to the signal generated by the full subtraction of the previously recorded sweep duration code. This signal enters the control unit 2. which puts the device in read mode. Then, from block 2, an erase and write command is sent to block 24 of memory, which is ready to be written and is in standby mode. The control unit 2 enables blocks 3 and 4. On the signal grid of the CRT 1, a read and converted signal appears in the form of small amplitude pulses, the phase of which carries information about the amplitudes of discrete samples registered on the screen of the CRT 1 signals. These pulses arrive at the input of the amplifier 25 readings, from the output of which the generated signals arrive at the information input of the memory block 24. - After the reading process is completed, the control unit 2 places the memory unit 24 in the playback mode, and the readout signal scanner 3 is started from the memory unit 24, which starts to operate in a cyclic mode, and the display appears on the screen of the display unit 26 the process under study. In addition, in display unit 26, there is a special output for inputting information into a computer.
