Description

one

The known digital voltmeters of instantaneous values of pulsed electrical signals, containing amplitude-time and time — a pulse converter, pulse counters, a control unit, and a memory unit, are characterized by an insufficient sampling rate and a significant minimum gate duration, which limits information on impulse processes of less than 1 ms and makes it possible to study the pulse shape of ms and nsec-duration ranges.

To increase the tempo of samples of instantaneous values and reduce their duration while ensuring high accuracy of single measurements of instantaneous values, a storage electron tube with a collector, an input limiter, a scanner unit, switches, an amplifier, a circuit for setting coordinate measurements along the time axis and a rewriting scheme are introduced into the voltmeter connected in such a way that the vertical deflection plates of the tube are connected through one of the switches to the output of the amplifier connected at the input to Odom limiter and scans unit; horizontally deflecting plates are connected via another switch with the scanner unit and with the installation scheme of the measurement coordinate along the time axis, and the collector of the tube is connected to the input

let us have an inverter connected to the output with a counter input, the triggers of which are connected by a rewriting circuit to the trigger trigger circuits of the counter connected n; an input with an output of the amplitude-time converter of the compensating voltage supplied to the limiter of the input circuit. yala

The drawing shows a block of what is the insulated device.

The device contains an inputTevTb / with adjustable reference source 2 at the input connected with amplitude-time 3 and time-pulse 4 transducers with a binary-decimal counter. The triggers of the counter 5 are connected via rewriting circuit 6 with the trigger chains of the triggers of counter 7, the state combinations of which are stored by the memory block 8.

The output of the limiter 1 is connected to the amplitude of the vertical deflection of the electron beam 9 and through the switch 10 to the plates.

Plate X horizontal deflected. ZELT through the switch 12 are connected either to the block 13 of the calibrated sweeps, or to the block 14 of installation of the measurement coordinate and its time axis.

The collector ZELT 11 is connected to the circuit

rpcn-impu.chspo converter /.), r, (i; i, which is connected to the input of the counter 7.

The switching of the functional connections between said circuits is performed by control block i.

The device works as follows.

When the input pulse arrives on the grabber, a vertex is allocated, the image of which is recorded on the ZELT target.

The limiter level is converted by converters 3 and - into a series of pulses n recorded in two-ten code in counter 5. ZELT operates in 3aHOMrniaiiiu mode and stores recorded information for a long time.

At the end of the recording, the control unit 16 switches the switch X from the output of the block 13 with the help of the switch 12 to the output of the block 14, which is used by the operator to determine the location of the cells in accordance with the times of the program.

At the intersection of the alpine reliefs of the helicopter and the sweep and the rape, the recording of the pulse of the explored pulse from the ZELT collector is taken m (pulse, which enters the flow of the first emulsions and the output of the converter / 5.

In counter 7, the input of which is m1 pulses from the converter 15, is previously uncoupled with the help of circuit 6, the combination stored in counter 5. When the response factor is equal to P, the iite is transformed (1 digit and 1 time) (with lo ontn ZELT) transformative
