Relay Matrix Switch Command Reference 45Chapter 3
OUTPut
The OUTPut subsystem selects the source of the output trigger
generated when a channel is closed during a scan. The selected output
can be enabled, disabled, and queried. The three available outputs are
the ECLTrg and TTLTrg trigger buses and the E1406 Command Module
front panel Trig Out port.

OUTPut:ECLTrg[:STATe]
OUTPut:ECLTrgn[:STATe] <mode> selects and enables which ECL
Trigger bus line (0 or 1) will output a trigger when a channel is closed
during a scan. This is also used to disable a selected ECL Trigger bus
line. n specifies the ECL Trigger bus line (0 or 1) and mode enables

(ON or 1) or disables (OFF or 0) the specified ECLTrg bus line.
Parameters
Comments Enabling ECL Trigger Bus: When enabled, a pulse is output from the
selected ECL Trigger bus line (0 or 1) after each channel is closed during
a scan. If disabled, a pulse is not output. The output is a negative-going
pulse.
ECL Trigger Bus Line Shared by Switchboxes: Only one switchbox
configuration can use the selected trigger at a time. When enabled, the
selected ECL Trigger bus line (0 or 1) is pulsed by the switchbox each
time a scanned channel is closed. To disable the output for a specific
switchbox, send the OUTPut:ECLTrgn OFF or 0 command for that
switchbox.
