Response
The 3152B returns the current trigger delay time value in sample clock cycles.
TRIGger:DELay {OFF|ON|0|1}(?)
HS Syntax: 0188A<0|1>(?)
Description
Use this command to toggle the delayed trigger feature. The trigger delay command affects the generator
only after it has been programmed to operate in interrupted run mode. Set the 3152B to interrupted run mode
using the INIT:CONT OFF command.
Range
Type
Default
Description
0-1
Discrete
0
Toggles delayed trigger mode.
Response
The 3152B returns 0 or 1 depending on the selected option.
TRIGger:DELay:Time <time>(?)
HS Syntax: 0156A<float>(?)
Description
The trigger delay time parameter defines the time that elapses between the receipt of a valid trigger signal
until the initiation of the first output waveform. Trigger delay can be turned off and on using the TRIG:DEL
<0|1> command. The trigger delay time command affects the generator only after it has been programmed to
operate in interrupted run mode. Modify the 3152B to interrupted run mode using the INIT:CONT OFF
command.

Description
<time>
100e-9 to 20
Numeric
100e-9
Programs the trigger delay time. Programming
resolution is 20 ns across the range.
Response
The 3152B returns the current trigger delay time value.
TRIGger:GATE:MODE {LEVel|TRANsition}(?)
HS Syntax: 0157A<0|1>(?)
Description
Toggles the 3152B between gating on start and stop pulses (TRANsition) or on threshold crossings (LEVel).
The trig:slop command defines the polarity of both modes. Select the source as either the front panel TRIG IN
connector or from one of the backplane trigger lines. Note that if you want to control the trigger level threshold,
you can only do it if you are using the front panel input. This command affects the 3152B only after it is set to
INIT:CONT OFF mode.
Parameters
Name
Type
Default
Description
LEVel
Discrete
LEV
Selects a level with a programmable threshold at the
external trigger input as the gating source.
