SENSe:GATE:STARt:DELay:SOURce
Syntax
[SENSe:]GATE:STARt:DELay:SOURce {IMMediate | TIME | EVENts}
[SENSe:]GATE:STARt:DELay:SOURce?
Description
This command selects whether time or input events (edges) are used to delay the gate open (start) when
advanced gating is enabled (SENSe:FREQuency:GATE:SOURce, SENSe:TINTerval:GATE:SOURce, or
SENSe:TOTalize:GATE:SOURce set to ADVanced with the appropriate measurement function selected).
Remarks
l Selecting IMMediate disables the gate open delay.
l The delay starts when the gate enable is received.
l If SENSe:GATE:STARt:SOURce is set to IMMediate, the gate will open immediately following the end of
the trigger delay.
l If SENSe:GATE:STARt:SOURce is set to EXTernal, the gate will open after the delay. The delay starts on the
selected edge on the source selected by SENSe:GATE:EXTernal:SOURce, which must occur after the end of
the trigger delay. Events that occur during the trigger delay are ignored.
l The instrument sets the gate open delay source to IMMediate after a Factory Reset (*RST command) or an
Instrument Preset (SYSTem:PRESet command).
Return Format
The query returns the current gate open delay 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.
