Vg. Brovchenko, GENERATOR OF CURRENT PULSES WITH POLARITY INVERSION FOR RESISTANCE MEASUREMENTS, Instruments and experimental techniques, 37(2), 1994, pp. 172-173
The generator produces current pulses whose polarity can be switched v
ia the CAMAC bus. Measuring resistance with two polarities produces mo
re accurate results. The amplitude of the current pulses is 10 mA, the
relaxation time to within 0.01% is about 100 musec.
