Enabling Gate Signals on the ‘Gate In/Out’ BNC
For timing and synchronization with other instruments gate signals from
sources Time (internal), IMMediate (internal), and INPut[1]/INPut2
(Chan 1 and Chan 2 softkeys) can be routed to the rear panel ‘Gate In/ Out’ con-
nector and assigned a polarity using the commands:
OUTPut[:STATe] {OFF|ON}
OUTPut[:STATe]? (query form)
OUTPut:POLarity {NORMal | INVerted}
OUTPut:POLarity? (query form)
ON enables “Gate Out” - gate signals are routed to the rear panel BNC. OFF dis-
ables “Gate Out” - the BNC is an external (“Gate In”) source. Therefore,
OUTPut:STATe OFF must be set when the gate source is EXTernal.
NORMal - the polarity of the gate signal output from the "Gate Out" BNC is a
rising (positive) edge. INVerted - the gate signal polarity is a falling (nega-
tive) edge.
