Description

Compelling voltage detector5: Vertically connected to the first input of the first electronic commentator, and a horizontal compensating voltage former connected to the first input of the second electronic switch provided with vertical and horizontal travel voltage generators; the outputs are connected to the second inputs of the first electronic switch. and the second electronic switches, the third inputs connected to the fourth output of the switch, the second and third inputs of which are connected to the second and third outputs of the first electron th switch, fifth and sixth inputs - with the second and third outputs of the second electronic switch and the first and second vyhodys first n second inputs of the digital voltmeter.

The structural electrical circuit of the proposed device is shown in the drawing.

The device consists of an amplifier 1 vertical deflection, a cathode ray tube 2, a switch 1, a generator 4, a sweep voltage, a digital voltmeter 5, a first and a second electronic switch 6 and 7, a vertical compensator 8, and a compensator 9 horizontals, a vertical displacement generator 1O, and a horizontal displacement voltage generator 11.

The proposed device works as follows.

When using the device as an electron-beam oscilloscope, switch 3 is in the Off position. In this case, the digital voltmeter 5 is turned off, the vertical displacement voltage driver 1 is connected via a switch 6 to the second input of the vertical deflection amplifier 1, the horizontal displacement voltage driver 11 is connected via a switch 7 to the second input of the sweep voltage generator 4.

- When measuring the amplitude parameters of the signal under study, the switch 3 is set to the voltage position. In this case, the switches 6 and 7 operate in the auto-oscillatory mode. The switch 6 periodically connects to the second input of the amplifier 1. vertical deviation either the driver 10 of the displacement voltage along the vertical, or the driver 8 of the compensating voltage along the vertical. Switch 7 periodically connects to the second input of the generator 4 eg: keni

sweep, the horizontal voltage shaper 11, and the shaper 9 compensate (its horizontal voltage. The first input of the digital voltmeter 5 is connected to the vertical shaper 10, no vertical movement, the second input to the shunt vertical voltage compensator 8 of the vertical 8. The third input of the digital voltmeter 5 is connected to the third output of the vertical deflection amplifier 1.

In this case, on the screen of the cathode-ray tube 2, two images of the signal are found, displaced relative to each other in vertical and horizontal directions. To measure the magnitude of the voltage between the vertical and lower points of the

Sitnal mowing with the help of the gamers 8 and. 9 compensating stresses vertically and horizontally combine the top 1 point of the shifted image of the sign with the lower point of the unmixed image,

The digital voltmeter 5 measures the voltage at the outputs of the driver 1O of the displacement voltage along the spindle and the driver 8 compensates the voltage of the receiver and returns the measured voltage to the third input of the digital voltmeter 5, the measurement result It is digitally digitized with Be7x; TVs are dimensions.

When measuring the time parameters of the signal under study, the switch 3 is set to the Time position. In this case, the switches 6 and 7 operate in self-oscillating mode, the first input of the digital voltmeter 5 is connected to the horizontal voltage regulator 11, the second input to the horizontal compensating voltage generator 9, and the third digital input voltmeter 5 The output of the sweep voltage generator 4 receives information about the set ratio of the spread.

To measure the time scale of the 1Herval between the upper and lower points of the image
