Description

an impulse whose input is connected with an adder-ZykhoD01M, inputs of a key to the outputs of the amplifiers, the input of the start-impulse formarifier is connected to the third output of the boom Oh of the sweep and Si, OX, ron.

In the drawing. An electronic diagram of the device is represented.

The device consists of a measuring elec- tron, but a beam and / indicator /, between euran: and horizontally deflecting plates of which are anodocontacts, unit 2 sweep and synchronization, amplifiers 3 and 4, detectors 5 and 6, com 7, digital the compensator 8, the adder 9, the formers 10 of the stop-pulse and the start-pulse //, the key 12, the HCipaTOpa 13 counting pulses, the count} of 14 pulses and the digital indicator / 5.

The device works as follows.

The signal under study is taken at the first height of the flap deflection plate of the measuring indicator /. The sweep voltage, synchronized with the signal under consideration, M, appears from the left and second outputs of block 2 (sweeps to horizontal deflecting lines of indicator 1. Signals from the outputs of the anodes-contacts are amplified by 3 watts. 4, they are detected by detectors 5, 6 and compared by comparator 7.

The output signal of the computer; the rapper 7 controls the digital compensator 8, which produces a constant compensating voltage applied to the second core and the alternating plate. After completion of the compensation process, the DC voltage from the output of the digital capacitor 8 is a measure of the measured instantaneous voltage value of the signal under study. The result, nn, is displayed on a digital indicator 15.

The measurement of the time interval: the shaft between the beginning of the times; B: the terminal and the instantaneous value of the search, which is selected by the operator during visual control on the screen, is made simultaneously with the measurement of the instantaneous value of the adjusted and the OS; is emaciated.

H. Mnyvibc start-up raz, the cable from the output of the block, screw-in1, 2 starts the shaper // start-impulse, which opens the switch 12 and prevents the passage of counting puls with the pulse generator 13 on the counter of pulses M.

Stop pulse,: a concealing key 12, is formed by a pho (pin 10, triggered by the output signal of the adder 9, to the inputs of which are received from the outputs of amplifiers 3, 4 signals, 1 picking up at the time of a dresree and an electron beam .contacts indicator, /. The number of counting impulses.v recorded in the counter 14 and indicated by a digital indicator 15, P (proportional to the time interval

between the start of the test and the selected instantaneous value of the voltage of the test ramp.

The time interval — between two produced instantaneous: n signal values is measured in terms of signal and reception: first, measure the time interval between the first and the first sweep and the first m-signal of the first signal, then between the beginning of the sweep and the second instantaneous value of the signal, and then subtract the first measurement from the second.

The invention makes it possible to measure the amplitude and temporal parameters of pulses with a baptism of about 0.1% simultaneously with one instrument.
