Keysight 53220A/53230A User’s Guide 197
– holdoff source TIME holds off the gate stop (close) for a period set by the
command:
[SENSe:]GATE:STOP:HOLDoff:TIME {<time>|MINimum|MAXimum|
INFinity|DEFault}
[SENSe:]GATE:STOP:HOLDoff:TIME? (query form)
Note for frequency, frequency ratio, average period, PRF, and PRI measurements,
the minimum gate stop (close) holdoff time is 100 usec for the 53220A, or 1 usec
for the 53230A.
INFinity or +9.9E+37 is accepted only for the TOTalize measurement function.
When selected, the gate remains open until an ABORt or *RST command or a
device clear is received.
Gate stop source
The gate stop source determines when the measurement gate is closed following
the stop hold off.
Setting a gate stop source does not apply to rise/fall time, duty cycle, pulse
width, phase, and single period measurements. These measurements complete
automatically on the next appropriate edge on the input channel.
