CNPM 0021 is a high gain, high voltage electrostatic excitation amplifier Its output AC signal can be superimposed on a DC bias voltage of either 200 V DC or 800 V DC.
The input signal to the PM 0021 is provided via a standard BNC connector and can be any signal up to 1 V RMS. The PM 0021 amplifies this signal by 40 dB (i.e., 100 times), delivering a maximum output of 100 V RMS.
PM 0021 provides three output interfaces: pure AC output, AC+200V DC output, and AC+800V DC output.
