4.3.2 Status Output Interface

The status output is a feature that reports the Analyzer conditions via contact closures on the rear panel. The closures are available on a 50 pin connector on the rear panel. The contacts are NPN transistors which can draw up to 50 mA of DC current. The pin assignments are listed in the Table below.
