:DELay <n>
:TRIGger[:SEQuence[1]]:DELay <n> Set trigger model delay
Parameters <n> = 0 to 999999.999 Specify delay in seconds
DEFault 0 second delay
MINimum 0 second delay
MAXimum 999999.999 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 of the trigger model. After the pro-
grammed event occurs, the instrument waits until the delay period expires
before performing the Device Action in the Trigger Model.
The delay time can also be set by using the AUTO parameter. If AUTO is
set to 1 or on, the delay period is enabled and will occur. If AUTO is set
to 0 or off, the delay period is not enabled and no delay will occur.
:SOURce <name>
:TRIGger[:SEQuence[1]]:SOURce <name> Specify measure event control source
Parameters <name> = IMMediate Pass operation through immediately
EXTernal Select External Triggering as event
TIMer Select timer as event
MANual Select manual event
BUS Select bus trigger as event
Query :SOURce? Query programmed control source.
Description These commands are used to select the event control source. With IM-
Mediate selected (do not confuse :SOURce IMMediate with :INITiate:IM-
Mediate), operation immediately starts.
A specific event can be used to control operation. With EXTernal select-
ed, operation continues when an External Trigger is received.
With TIMer selected, the event occurs at the beginning of the timer inter-
val, and every time it times out. For example, if the timer is programmed
for a 30 second interval, the first pass through the control source occurs
immediately. Subsequent scan 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.
With BUS selected, the event occurs when a GET or *TRG command is
sent over the bus.
