However, the known devices for registering one-time fast-flowing processes do not 5 allow to register streams of one-time processes.

The aim of the invention is to extend the functionality of the device.

The goal is achieved by additionally introducing a digital phase discriminator, an additional memory block and a process analysis BLK, with the control inputs of the memory blocks and the process analysis block connected to the corresponding outputs of the control block, the information input of the memory block associated with the output digital phase discriminator, and the output is from the information input of the analog block 1; for the irits .ssov, the control and information outputs of which are connected to

The introduction of new nodes and communications greatly expands the functionality of the proposed device.

The described device is shown in the drawing.

Before registering the process under study, the device is prepared. The first stage is the preparation of the screen of the electron-beam tube 1 (CRT) for recording, which is carried out by issuing a command from the trimmer unit 2 to the scanner reader 3 and the second illumination unit 4.

The power supply unit is shifted to the position corresponding to the preparation mode of the electron-beam tube (CRT). At the same time, a rectangular raster of a television type is displayed on the screen. The second stage of preparation consists in that the control unit 2 transfers the switched power source 5 to the recording mode, sends a command to the calibration unit 6 and to the driver of the starting pulses 7, which starts the writing scanner 8n the first block of the backlight 9, thereby reproducing the calibration light. a sinusoid on a cathode ray tube corresponding to a given sweep range. In this case, the control unit 2 performs a shift of the recording beam in the screen field, producing a recording of a sine wave in the lower part of the screen floor. Then, the trigger pulse generator 7 and the blocks 8 and 9 are restarted.

The recording beam level is shifted above the recorded calibration sine wave (i.e., a "zero rainfall is recorded), after which the beam is shifted to a position above the" zero line. "

The device is in standby mode. With the arrival of the first signal under investigation, the driver that triggers blocks 8 and 9 is triggered, after which block 8 is blocked at the input, and the signal of the process under study is recorded on the screen of the CRT and goes to the input of the coaxial tube system through the delay block 10 and 9. The blocking signal from block 8 enters the control unit 2 and signals the end of the recording process ..

- Next, the process of reading the first signal under investigation begins. The readout process begins with the supply by the control unit 2 of a voltage to the switched power source 5, which converts it to read mode 1M. Then, from block 2, a command is issued for preparing to write to memory blocks 11, 12, after which both memory blocks are ready for recording and are in standby mode.

The control unit 2 starts blocks 3 and 4. On the signal grid 13, a read-out transformed signal in the form of pmpulses of small amplitude appears, the phase of which carries information about the amplitudes of the discrete samples registered on the CRT signal. These pulses are fed to the input of the read amplifier 14, from the output of which the generated signals are sent to the information inputs of the additional memory block 12 and the digital phase discriminator 15, to the second input of which the pulses of the reference signal come from the control unit 2.

The reference pulses give the origin of the phase shift of the information pulses.

The digital phase discriminator 15 measures the phase information pulses by the method of sequential counting and outputs a parallel binary code to the information input of the memory block 11,

characterizing each discrete sampling of the amplitude of the recorded signal. Simultaneously, the read signals from amplifier 14 are recorded in an additional memory block 12, and in the preparation mode of the CRT to record the subsequent signal, block 12 is switched to the playback mode, and the screen of the display process 16 is displayed on the screen of the display unit 16. At the end of the process

The read of the first CRT signal recorded on the CRT screen is switched to the preparation mode for recording the next signal. The cycle. The process of recording signals on a CRT screen, reading and writing to the memory block, and Ends after the registration of the studied stream of one-time fast processes. During this cycle, an additional information block 12 is periodically updated. With

In memory 11, this accumulates information in the form of a series of binary numbers, which are digital equivalents of the discrete samples of all the single signals of the stream under study.

At the end of the registration process, the device is switched to the analysis and playback mode. For this, the control unit 2 is instructed to transfer the memory unit 11 to the read mode.

The read information together with the synchronization signal from the control unit 2 is fed to the input of the process analysis unit 17, which sequentially retrieves information, transforms it, analyzes it and generates information about the ordinates of the amplitude distribution of the stream of one-time processes.

The process of displaying the registered information involves the operation of the device in two modes;

1. The indication mode of any of the registered one-time processes.

2. A mode for indicating the amplitude distribution of a stream of one-time high-speed processes.

In the observation mode (indication) of the form, according to the program specified by block 2, process analysis block 17 selects information from any of the registered one-time fast-flowing processes from memory block 11, converts and writes to an additional memory block 12. At the end of the recording, block -12 according to the command block of the control unit 2, it is switched to the playback mode.

In the amplitude distribution indication mode, the information coming from the process analysis unit 17 is similarly loaded into an additional memory block 12 and is displayed on the display unit 16 in playback mode. When the display unit 16 plays, the image of the amplitude distribution form appears studied stream of single fast processes (or the form of any of the registered single processes).

Thus, the proposed device allows one to record streams of one-time fast processes, to carry out their statistical analysis, and to carry out a visual observation of both the amplitude distribution of the stream and the form of individual single signals, which makes it possible to significantly extend the functionality and scope of this device.
