Parameters
Comments Abbreviated Syntax: OUTPut subsystem commands [:EXTernal] and
[:STATe] are optional subcommands. The OUTPut command can be
abbreviated by executing OUTPut ON or OUTPut OFF.
Enabling Trig Out Port: When enabled, the Trig Out port is pulsed each
time a channel is closed during scanning. When disabled, the Trig Out
port is not pulsed. The output pulse is a +5 V negative-going pulse.
Trig Out Port Shared by Switchboxes: Once enabled, the Trig Out port
may be pulsed by the switchbox each time a channel is closed in a
switchbox during scanning. To disable the output for a specific
switchbox, send the OUTPut[:EXTernal] [:STATe] OFF or
OUTPut[:EXTernal][:STATe] 0 command for that switchbox. The OUTP
OFF command must be executed following use of this port to allow other
instrument drivers to control the Trig Out port.
