17-104 SCPI Command Reference
:DELay <n>
:TRIGger[:SEQuence[1]]:DELay <n> Set trigger layer delay
Parameters
<n> = 0 to 999.9999 Specify delay in seconds
DEFault 0 second delay
MINimum 0 second delay
MAXimum 999.9999 second delay
Query
:DELay? Query the programmed delay
:DELay? DEFault Query the *RST default delay
:DELay? MINimum Query the lowest allowable delay
:DELay? MAXimum Query the largest allowable delay
Description
The delay is used to delay operation in the trigger layer. After the pro-
grammed trigger event occurs, the instrument waits until the delay period
expires before performing the Device Action.
:SOURce <name>
:ARM[:SEQuence[1]][LAYer[1]]:SOURce <name> Specify arm event control source
:TRIGger[:SEQuence[1]]:SOURce <name> Specify trigger event control source
Parameters
<name> = IMMediate Pass operation through immediately
TLINk Select Trigger Link trigger as event
TIMer Select timer as event
MANual Select manual event
BUS Select bus trigger as event
NSTest Select low SOT pulse as event
PSTest Select high SOT pulse as event
BSTest Select high or low SOT pulse as event
NOTE
Only IMMediate and TLINk are available as trigger layer control sources.
Query
:SOURce? Query programmed control source
Description
These commands are used to select the event control source. With IMMedi-
ate selected, operation immediately continues.
A speci
fi c event can be used to control operation. With TLINk selected,
operation continues when a trigger pulse is received via the Trigger Link.
NOTE
The following control sources are not available for the trigger layer.
With TIMer selected, the event occurs at the beginning of the timer interval,
and every time it times out. For example, if the timer is programmed for a
30 second interval, the
fi rst pass through the control source occurs immedi-
ately. Subsequent arm events will then occur every 30 seconds. The interval
for the timer is set using the :TIMer command.
With MANual selected, the event occurs when the TRIG key is pressed.
