A STANDARD DEVICE FOR REPRODUCTION AND MEASUREMENT OF PARAMETERS OF IMPULSE SIGNALS

The standard was established and is in operation since 2007

The composition of the standard device:

  • calibrator of oscillographs FLUKE 9500 B;
  • broadband oscillograph Agilent 86100 C;
  • measuring device K2-76

Metrological characteristics:

  • in signal reproduction mode:

- constant current voltage range:

from ± 1 mV to ± 200 V at the load of 1 MOhm;

from ± 1 mV to ± 5 V at the load of 50 Ohm;

- accuracy of the voltage setting of the continuous current – ± (0,025 % +25 mkV);

- rectangular signal amplitude:

from 40 mkV to 200 V at the load of 1 MOhm;

from 40 mkV to 5 V at the load of 50 Ohm;

- amplitude setup error:

<1 mV – ± (0,1 % + 10 mkV);

>1 mV – ± (1 % + 10 mkV);

- change of voltage of positive and negative polarity with the building-up time at the output, loaded at resistance 50 Ohm:

500 (± 35) ps at the amplitude from 5 mV to 5 V;

150 (± 25) ps at the amplitude from 5 mV to 3 V;

70 (± 12) ps at the amplitude from 25 mV to 2 V;

25 (± 3) ps at the amplitude from 425 mV to 575 mV;

- calibrate signal of oscillograph sweep duration within the range from 450 ps to 5 s;

- setting error from ± 0,25 ppm to ± 3 ppm

  • in signal measurement mode:

- pass band from 0 to 50 GHz

- standard deviation of noise voltageне does not exceed 1 mV;

- the range of input signals voltage measurement from 10 mV to 1 V;

- relative measurement error of direct current voltage ≤ ± 0,4 %;

- relative measurement error of alternating current voltage within the frequency band from 0 to 37,5 GHz ≤ ± 2 %;

- measurement range of time intervals from 20 ps to 10 s;

- pass band from 0 to 200 MHz;

- voltage range of measured signals from 10 mV to 40 V;

- measurement range of time intervals from 3 ns to 1000 s

Scope of application:

Standard device is meant for reproduction and measurement of impulse signals, build-up time/fall time, non-uniformity of the top in order to define metrological characteristics of the oscillographs, pulse generators, measuring instruments of time signals, time-domain voltmeters and conducting high-precision measurements of the parameters of appliances.
