A standard ac plug receptacle for the 120 or 220 Vac power mains. Plug is
compatible with any of the three power cord options available for the 1720/1721
Vectorscope.

3. AUXILIARY
A 9-pin connector used to interface with the 1730-Series. Auxiliary control
consists of a signal line (Line Strobe) and a serial interface. The serial interface
