198 Keysight 53220A/53230A User’s Guide
The specific command which sets the gate stop source is:
[SENSe:]GATE:STOP:SOURce {IMMediate|EXTernal}
[SENSe:]GATE:STOP:SOURce? (query form)
– gate source IMMediate stops (closes) the measurement gate immediately
following any gate stop hold off.
– gate source EXTernal sets the gate stop source to be specified by the
command:
[SENSe:]GATE:EXTernal:SOURce {EXTernal|INPut[1]|INPut2}
[SENSe:]GATE:EXTernal:SOURce? (query form)
– gate source EXTernal is the counter’s rear panel ‘Gate In/Out’ BNC.
– gate source INPut[1] and INPut2 (not available with time interval
measurements) are the counter’s channel 1 and channel 2 inputs (front or rear
panel - Opt. 201).
CONFigure and MEASure do not change the gate stop source setting. Following
a reset (*RST) or instrument preset (SYSTem:PRESet or Preset key), gate stop
source EXTernal is selected.
OUTput:STATe OFF must be set when using gate source EXTernal. See
“Enabling gate signals on the ‘gate in/out’ BNC” for more information and for
information on using gate signals to synchronize other instruments.
