The device contains a cathode-ray tube 1 with a memory (CRT), control unit 2, read scan unit 3, read light unit 4, counter 5, switched power supply b, start pulse generator 7, write scan unit 8, backlight block 9 records, delay unit 10, additional driver 11, digital-analog converter 12 decoder 13, inverter 14, comparison circuit 15, second memory block 16, first memory block 17, signal grid 18, read amplifier 19, /, block 20 display, digital phase discriminator 21, block 22 en aliza processes.

The information display device operates as follows.

Before registering the processes studied, the system is prepared. The first step is to prepare the screen of the electron-beam tube 1 (CRT) for recording, by sending a command from the control unit 2 to the readout unit 3 and the readout light unit 4, writing to the counter 5 a code inverse to the code of the recorded pulse train, taking into account the corresponding possibilities of the sweep duration selected for registration. The switched power supply is switched to the position corresponding to the preparation mode of the CRT. At the same time, a rectangular raster of a television type is displayed on the screen of a CRT. The second stage of preparation is that the switched power supply 6 is switched to the recording mode. After that, the system is in standby mode. The first test signal of the series, arriving at the system input, is fed to the input of the trigger pulse generator 7, which triggers the sweepers 8 and the recording light 9, while on the screen of the CRT 1 the first signal of the tested series is recorded, which enters the input of the coaxial CRT system through the unit 10 delay to the response time of blocks 8 and 9. At the same time, from the reverse of the sweep of the block 8 by the shaper 11, a signal is generated that enters the input of counter 5 and increments the counter code by one, which displaces with If the analogue converter 12 starts the recording beam by 2 mm in the direction of the sweep, thereby marking the subsequent recorded signal of the series.

The following signal of the 1st serialized series is fed to the input of the system and is recorded on the CRT screen in the same way. In this case, CRT targets will be recorded n signals on one scan, each for the entire scan duration, but marked by a shift in the start of the scan. According to the last signal of the selected recorded series, the counter 5 is set to the position in which the decoder 13 allows the pause pulse to pass through the inverter 14 and the comparison circuit 15 to the input of the control unit 2, transferring the read time system. The readout process begins with the supply by the control unit 2 of a voltage to the switched power source 6, which puts it in readout mode. Then, from block 2, a command is issued to prepare to write to blocks 16 and 17 of memory, after which both blocks of memory are ready for recording and are in idle mode.

Control unit 2 launches Oloki 3 and 4. Signal grid 18 contains read and transformed signals in the form of small amplitude pulses, the phase of which carries information about the amplitudes of discrete samples recorded on a series CRT screen. These pulses go to the input of the read amplifier 19, from which output the generated signals go to the second information input of the second memory block 16, where they are recorded. Then, at the command of the control unit, the memory unit 17 is switched to the cyclic reproduction mode of the recorded information on the screen of the display unit 2. The reproduced information is analyzed by the researcher on the screen of the display unit and the consecutive ordinates are selected, corresponding to the first and

0 then the n-th pulse of the series, and the corresponding commands are sent from the gravitating unit to the digital phase discriminator 21 to select the memory block 16 of this information, convert it to parallel binary codes and write to the first memory block 17. As a result, in block 17, memory is recorded, set sequentially, information about the orders of each process, i.e. information about the ordinates of the registered signals of the series from the parallel memory in block 17 is transformed into a sequential one, since all the ordinates of all processes are set in time sequentially, which allows for further analysis to consider the forms of each process independently. But when the process of recording the first series of pulses is completed in the first memory block 17, the system is switched to the preparation mode for recording the next series of the stream under study.

Loop Recording Process

5 signals to the CRT screen, reading, writing to the second memory block 16, and then to the first memory block 17 is completed after registration of the test stream of single series

0 fast processes. At the end of the registration process, the device is placed in the analysis and display mode of the registered information. For this purpose, from block 2 of the control unit, a command is given to transfer the block 17 of the memory to read mode. The read information together with the synchronization signals from the control unit 2 is fed to the input of the process analysis unit 22, which carries out the sequential retrieval of information, its conversion, analysis and generation of information about ordinates of the amplitude distribution in the series, as well as amplitude distribution of the average power envelope over the series m ..

The process of displaying the recorded information provides for two modes of operation B: the display mode of any of the registered one-time processes of any flow series and the display mode of the amplitude distribution in the series or the amplitude distribution of the average power envelope by series. In the monitoring mode (indication) of the form according to the program specified by unit 2 , process analysis unit 22 selects information from any of the registered one-time high-speed processes from memory block 17, transforms and records s in the memory unit 16. When the recording is completed, the memory block 16 is switched to the playback mode. In the mode of indication of amplitude distributions, information from block 21 is similarly recorded in block 16 of memory and in playback mode is displayed on the screen of block 20 of indication. When playing on the screen of the display unit 20, an image of the amplitude distribution patterns or the shape of any of the registered single processes appears.

Thus, the proposed system allows the operator to analyze and display on the indicator screen information about a series of one-time fast processes, by increasing the throughput of the target of the storage electron-beam tube that passes one cycle of preparation.
