5 Triggering and Gating
144 Keysight 53210A User’s Guide
When using external source
INPut[1]
, the channel selected as the gate source
cannot be the same channel on which the measured signal is applied. That is, the
gate source channel cannot be involved in the measurement.
Enabling Gate Signals on the ‘Gate In/Out’ BNC
For timing and synchronization with other instruments, gate signals from source
TIME
(internal) and
INPut[1]
can be routed to the rear panel
‘Gate In/ Out’ connector 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 from sources
TIME
and
INPut[1]
are
routed to the rear panel BNC.
–
OFF
disables “Gate Out” - the BNC is an external (“Gate In”) source. Therefore,
OUTPut:STATe OFF
must be set when the gate source is
EXTernal
.
NORMal
selects a rising (positive going) signal;
INVerted
selects a falling (negative
going) signal.
