A device ll is known, comprising an amplifier, a delay unit, a square pulse shaper, a write scanner, a read scanner and a backlight unit.

However, in such a device, due to the instability of the reference signal generator as well as the horizontal line scan generator for preparing the target for recording, there are target areas that are not prepared for recording (i.e., noisy target areas). Therefore, the target area of the recording pdei is underutilized.

The closest to the technical essence of the invention is a device 2J, containing an amplifier connected to a control electrode of a CRT, the delay unit, which is

The disadvantage of the inverted device 5: A limited frequency range of the recorded and displayed The aim of the invention is to expand the field of application of the device by increasing the frequency range of the input information signals. The goal is achieved by the fact that the proposed device contains a block for shifting a CRT beam, the input of which is connected to the corresponding output the control unit, and the decoder is with the corresponding CRT deflection plate and two switches, the inputs of which are connected to the corresponding outputs of the control unit. laziness.

The device works as follows. . .., .. Before registering the aeCdOE probes studied, the devices are prepared. At the first stage, this CRT is prepared for recording. (Preparation Osuschett2 is on commands coming from control block 2 to the offset unit 3 of the CRT beam (the beam is shifted beyond the lower target boundary) to the first switch 4 (sets the length of lines and frames of such dimensions 1.5-2 times exceed the sizes of the smaller ones) and on the switch 5 {the duration of the illumination is set according to the duration of the frame being set). After the above operations have been performed, the control unit 2 is instructed to transfer the power sources to the CRT preparation mode. Using a read out scanner 7 and a backlight unit 8 controlled via the switches 4 and 5 by the control unit 2, a television type raster is created which, when scanned against the target, prepares it for recording. At the second stage of preparation, the control unit 2 transfers the power source 6 to the recording mode, sends a command to the generator 9 and to the shaper 10. Which launches the recording scanner 11 and the backlight unit 12. When the calibration sinusoid is played, the CRT corresponding to the scan range is controlled by the control unit the recorded beam is shifted across the screen field, and a sine wave is recorded at the bottom of the screen floor. Shaper 10 and blocks 11 and 12 are then restarted. The level of the recording beam is shifted above the recorded calibration sinusoid {i.e. the zero line is recorded), after which the beam is shifted to the position above the zero line. With the current control unit 2, through switches 4 and 5, blocks 7 and 8 are placed in a mode in which these blocks form lines and a frame equal to the target size in a pairing mode and shift the readout beam to a level using a block 3 of the CRT beam. lower part of the target. At the same time, the device is in standby mode. With the arrival of the first signal under investigation, the driver 1O is triggered, which starts blocks 11 and 12, Block 11 is then locked along the bridge, and on the CRT screen, the signal of the process under test is recorded .57 is input to the coaxial system tubes through the delay unit 13 in the response time of blocks 11 and 12. The blocking signal from block 11 post. It goes to control unit 2 and signals the end of the recording process. The readout process begins with the supply by the control unit 2 of a voltage to the power source b, which puts it in readout mode. Then, from block 2, a command is issued to prepare for writing to memory blocks 14 and 15, after which the memory blocks of the record ready and are in standby mode. The control unit 2 through the switches 4 and 5 starts the blocks 7 and 8, which form a raster like a television, whose dimensions are equal to the size of the target. As a result of scanning by the cross-line raster of the target, a read and transformed signal in the form of small amplitude pulses appears on the controlled CRT electrode 16, the phase of which carries information about the amplitudes of discrete samples of the recorded CRT signal. These pulses are fed to the input of the amplifier 17, with the output of which the generated signals are sent to the information inputs of the memory block 15 and the analog-code converter 18, the second input of which receives the pulses of the reference signal from the control unit 2. The reference pulses set the beginning of the phase shift of the information pulses analogue code 18 measures the phase shifts of information pulses by the method of sequential counting and outputs to the information input of memory 14 a parallel binary code characterizing each discrete Bout the amplitude of the registered signal. Simultaneously, the read signals coming from the amplifier 17 are recorded in the memory block 15, and in the mode of preparing the CRT to record the subsequent signal, the block 15 is switched to the playback mode. In this case, the forms of the registered process are displayed on the screen of the display unit 19. At the end of the process Schy-yvani. the first CRT signal recorded on the CRT screen; i is transferred to the preparation mode for writing the next signal. The cyclic process of the CRT signals on the CRT screen, reading and writing to 2 memory block 14 ends after registration of the stream of one-time fast processes is registered. In the process of this cyt in the memory block 15, the information is periodically updated. In this case, I in the memory block accumulates information in the form of a series of binary numbers, which are digital, equivalent to discrete samples of all one-time 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, a command is sent from the control unit 2 to the memory unit 14 in the read mode. The information together with the synchronization signals from the control unit 2 is fed to the input of the primary signal processing unit 20, which performs sequential data acquisition, its transformation, analysis and generation of information about ordinates of the amplitude distribution of the stream of one-time processes. The process of displaying is registered. information provides for the operation of the device in two modes of indication of any registered process .. indication of the amplitude of the flow of a stream of one-time fast processes. In the mode of observation (indication) of the form according to the program specified by block 2, the unit of primary signal processing 20 selects information from any of the registered one-time fast processes from the memory block 14, converting to writing to the block 15 The recording unit is 15 k; the command from control unit 2 is transferred to the playback mode. In the amplitude distribution indication mode, the information coming from the signal processing unit 20 is similarly recorded in the memory block 15, and in the playback mode is indicated on the display unit 19 screen. When playing on the display unit 19, the amplitude image appears distribution of schsel; stream of one-time fast processes (or a form of any of the registered one-time processes).
