IPG 250, Pulse generator 250V

The pulse generator IPG 250 is designed for measuring the step response of high-impedance networks, for instance voltage dividers, oscilloscope probes etc. The generator excels by calibrated adjustment of output amplitude, short rise time and flat pulse top. The output pulse amplitude can be adjusted by use of a 10-turn potentiometer from 0 to 250 V. Positive and negative polarity can be selected.

PULSE GENERATOR 

IPG 250

 

The pulse generator IPG 250 is designed for measuring the step response of high-impedance networks, for instance, voltage dividers, oscilloscope probes etc. The generator excels by calibrated adjustment of output amplitude, short rise time and flat pulse top. The output pulse amplitude can be adjusted by use of a 10-turn potentiometer from 0 to 250 V. Positive and negative polarity can be selected.

 

Pulse output amplitude can be verified by external measurement with a digital voltmeter. The rise time and the flatness of the pulse top is guaranteed by the components used and the principle of operation

 

The external load impedance RL, CL is connected in series with 10 kW to a dc-power supply, whose output voltage is adjustable by a precision potentiometer from 0 V to ± 250 V.

The make connect switch S short circuits the voltage across the load impedance periodically. During short circuit, the generator's source impedance is 50 W.

 

 
Operational modes:
a)                 -                      dc-voltage output, 0 - 250 V
b)                 SINGLE         single pulse generation
c)                 REP.              repetitive pulse generation:

The repetition rate of pulse generation can be switched to app. 200 Hz (FAST) or to app. 1 Hz (SLOW). The rise time of the pulse slope generated by closing the switch S is less than 3 ns. For special applications, the 50 W-resistor can be removed.
