(query form)
CONFigure
and
MEASure
automatically set the gate source to
TIME,
and the
gate time to the value of their gate_time parameter.
To specify a gate time and source directly for totalizing:
// set gate time and source
SENS:TOT:GATE:TIME 10 // set gate time = 10s
SENS:TOT:GATE:SOUR TIME // set gate source
External Gate Sources
Gate sources
EXTernal, INPut[1],
and
INPut2
are external sources.
EXTernal
is the counter’s rear panel ‘Gate In/Out’ BNC, and
INPut[1]/INPut2
(represented by softkeys
Chan 1
and
Chan 2
) are the
counter’s channel 1 and channel 2 inputs.
External Gate Signal Polarity
When using the external gate sources, the polarity of the gate signal and there-
N O T E
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.
