:TRIGger Commands
The :TRIGger commands are used to set the trigger source type, trigger input edge type and trigger delay
as well as generate a trigger event.
Command List:
 :TRIGger[<n>]:DELay
 :TRIGger[<n>][:IMMediate]
 :TRIGger[<n>]:SLOPe
 :TRIGger[<n>]:SOURce
:TRIGger[<n>]:DELay
Syntax
:TRIGger[<n>]:DELay {<seconds>|MINimum|MAXimum}
:TRIGger[<n>]:DELay? [MINimum|MAXimum]
Description

Remarks
 Burst delay is only available for N cycle and Infinite burst mode. It is defined as the duration from the
time when the generator receives the trigger signal to the time when it starts to output the N Cycle (or
Infinite) burst.
 For the N cycle burst or Infinite burst in the external trigger or manual trigger mode
(
[:SOURce[<n>]]:BURSt:TRIGger:SOURce), the range of <delay> is 0 s to 100 s.
 For the N cycle burst in the internal trigger mode, the range of <delay> is from 0 s to
(
2us−×−

NPP
), and its range should be smaller than or equal to 100 s.
Wherein,
burst
P
——burst period;
waveform
P
——waveform period (i.g. the period of the burst function (Sine, Square, etc));
cycle
N
——number of cycles.
 When [<n>] is omitted, the system sets the burst delay of CH1 by default.
Return Format
The query returns the burst delay in scientific notation, with 7 effective digits. For example, 1.000000E+00
(the burst delay is 1 s).
Example
:TRIG:DEL 1 /*Sets the burst delay of CH1 to 1 s.*/
:TRIG:DEL? /*Queries the burst delay of CH1 and the query returns 1.000000E+00.*/
