QC Connectors

There are three (3) QC connectors on the rear of the 9412/9412A, 2 outputs and 1 input.

Channel 1 output -- a general-purpose pulse output, with programmable delay, pulse width, and pulse polarity. The maximum output voltage is adjustable and varies from 20 Volts open- circuit to 10 Volts when driving a 50 Ohm load. The maximum voltage is adjusted by a poten- tiometer located on the back of the 9412/9412A.
