Dual Channel HV Amplifier with Phase Inverter A800DI

dual-channel high-voltage linear amplifier with phase inverter A800DI

This unit contains two independent A800 amplifiers that share common ground reference and power supply. Please see A800 page for technical details.

It features also a low voltage phase inverter that inverts the signal applied to the input of channel 1. The resulting signal can then be connected to the input of channel 2 by means of a short BNC cable (supplied). As a result the two outputs operate in counter-phase. Connecting a load between the outputs effectively doubles the amplitude range. Please note that the load cannot have any connection to ground. Also, in order to see the signal over the load you must use two oscilloscope probes and use the math funtion.

The phase inverter is present in models A400DI and A800DI. The idea is illustrated below:
