Description

The invention relates to the field of recording and measuring parameters of one-time fast processes and can be used, for example, in the technique of a physical experiment.

Devices are known that record single rapid processes using electron beam tubes (CRT) with charge accumulation, which allow the processes to be recorded by means of a time-scale signal transform. At the same time, the known devices, in addition to the CRT with accumulation of charge, contain write and read channels, a switched collector power source, a secondary memory unit, and a process indication system. However, the known devices for registering one-time fast processes have an insufficient frequency range of the process registration and a low recording speed, which often makes it impossible to record high-speed one-time processes.

The proposed device is characterized in that a driver of trigger pulses is connected to the input of the delay unit connected to the coaxial deflection system of the tube, the signal from which is simultaneously fed to the inputs of the scanners and the backlight of the recording signals, and between the output of the read amplifier and the input of the digital processing unit The process indication is turned on by the secondary storage unit. The inputs of the trigger generator, the secondary memory block, the switched power source, the scanners and the recording light, the scan signals and the read light, as well as the inputs of the time calibration unit and the digital information processing and graphic registration units are connected to the registration control logic unit. This device clears the limits of measurement of parameters of one-time fast processes, their registration and memorizing 1 and.

The described device is shown in the drawing.

The device works as follows.

Before registering the process under study, the device is prepared.

The first stage is the preparation of the screen of the electron-beam tube (CRT) with memory to the recording, which is carried out by applying the voltage from the command from the registration process control unit 2 to the reading base units 3 and the reading light unit 4. The power supply is shifted to the position corresponding to the preparation mode of the CRT. At the same time, a rectangular raster of the television type is displayed several times on the CRT screen.

0 The second stage of preparation is that the registration process control unit switches the switched power supply 5 to the recording mode, sends a command to the time calibration unit 6 and to the trigger pulse generator 7, which starts the scanning units 8 and the recording backlight unit 9, thereby playing back The calibration sine wave on the CRT screen corresponds to this sweep range. At the same time, the registration process control unit displaces the recording beam along the screen field, recording a sine wave at the bottom of the screen floor. The pulse shaper and blocks 8 and 9 are then restarted. The level of the recording beam is shifted above the recorded calibration sine wave (i.e., a "zero line 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 signal being investigated, a trigger pulse shaper triggers, which triggers blocks S and I, after which block 8 of the write sweep is blocked on input, while on the screen of a CRT a signal of the process under investigation is recorded, which enters the input of the coaxial deflection system 10 through delay unit 11 By the time the S and 9 blocks are triggered. The blocking signal from the recording sweep block 8 after the arrival of the process signal arrives at the recording process control block 2 and signals the end of the recording process. Next, the readout process begins with the supply by the voltage unit 2 to the switched power supply 5, which puts it into the readout mode. Then, from block 2, an erase and write command is sent to block 12 of the secondary memory, after which block 12 is ready to write and is in mode. The registration process control unit starts blocks S and 9. On the signal grid 13, a read and transformed signal appears in the form of small amplitude pulses going at a strictly defined time; These pulses are fed to the input of the read amplifier 14, from the output of which the generated signal is fed to the information input of the secondary memory unit 12. After the reading process is completed, the block 2 switches the block 12 to the playback mode, and from the block 12, the scan scan block 3 is started, which starts to operate in a cyclic mode. When registering the process, an image of the process under study appears on the screen of the oscilloscope 15 of the display 16, and three signals are simultaneously transmitted to the three inputs of the oscilloscope: pa input y is the signal from the read scanner, input x is the signal from the registration control unit, and input Z is the signal from the information output of the secondary storage unit. The range of sweeps and amplifications of the oscilloscope, it is possible to obtain an image of the process under study at different amplitude and times of Hbix scales. Simultaneously with the operation of the oscilloscope, the information clock pulses from the secondary memory unit arrive at the corresponding inputs of the digital processing unit 17, at the output of which the coordinates of the process being studied and the calibration sinusoid appear as a binary digital code. The latter is fed to the input of the graphic registration unit 18, on the paper tape of which the recorded process under investigation is recorded simultaneously with the calibration sinusoid. In addition, in block 17 of the digital processing, there is a special output for inputting information into the EHTDM. Thus, the proposed device significantly expands the limits of measurement of the parameters of the studied fast processes, and also provides an opportunity for a long time to store the received information and record the subsequent information without destroying the previously registered with a high degree of accuracy. The graphic registration unit in the device ensures the registration of the process as direct graphic recording and its cyclic reproduction both on the screen of the oscillographic recorder at a convenient time scale and amplitude, and at the output intended for connecting a digital computing device.
