SENSe:GATE:STOP:HOLDoff:SOURce
Syntax
[SENSe:]GATE:STOP:HOLDoff:SOURce {IMMediate | TIME | EVENts}
[SENSe:]GATE:STOP:HOLDoff:SOURce?
Description
This command selects whether time or input events (edges) are used to hold off enabling the gate close
(stop) source when advanced gating is enabled (SENSe:FREQuency:GATE:SOURce, SENSe:TINTer-
val:GATE:SOURce, or SENSe:TOTalize:GATE:SOURce set to ADVanced with the appropriate meas-
urement function selected).
Remarks
l Selecting IMMediate disables the holdoff.
l The holdoff starts when the gate opens for totalize measurements. For other measurements, the holdoff
starts on the first input event after the gate opens.
l If SENSe:GATE:STOP:SOURce is set to IMMediate, the gate will close immediately following the end of
the holdoff.
l If SENSe:GATE:STOP:SOURce is set to EXTernal, the gate will close on the next selected edge on the source
selected by SENSe:GATE:EXTernal:SOURce following the end of the holdoff. Edges that occur during the hol-
doff are ignored.
l The instrument sets the gate close holdoff source to IMMediate after a Factory Reset (*RST command) or an
Instrument Preset (SYSTem:PRESet command).
Return Format
The query returns the current gate close holdoff source: IMM, TIME or EVEN.
Examples
The following example makes a frequency measurement on channel 1. The gate opens .1 sec after a neg-
ative edge on the Gate In/Out BNC, and, after .25 seconds, closes on the next positive edge on the BNC.
