34 Operation Overview
Port On/Off
Port is a general purpose output port that can be used to control an external device such as a relay for power supply test
purposes. The output is toggled on and off via the GPIB (PORT0 ON | OFF command). It cannot be controlled from the
front panel.
The Port output signal is a TTL compatible signal that becomes active (high level) when the PORT command is
programmed ON and becomes inactive (low level) when the PORT command is programmed OFF.
