Commands Listed in Alphabetical Order
Arguments CH1–CH4 specifies an analog input channel as the A edge trigger source.
EXT specifies an external trigger using the Aux In connector located on the front
panel of the oscilloscope.
LINE specifies AC line voltage.
Examples TRIGGER:A:PULSEWIDTH:SOURCE CH1 sets channel 1 as the pulse width source.
TRIGGER:A:PULSEWIDTH:SOURCE? might return :TRIGGER:A:PULSEWIDTH:
SOURCE CH1 indicating that channel 1 is the pulse width source.
TRIGger:A:PULSEWidth:WHEn
Sets or returns whether to trigger on a pulse that meets, falls outside, or within
the specified range of limits.

Related Commands TRIGger:A:PULSEWidth:WIDth
Arguments LESSthan argument sets the oscilloscope to trigger if a pulse is detected with
width less than the time set by the TRIGger:A:PULSEWidth:WIDth command.
than argument sets the oscilloscope to trigger if a pulse is detected with width
than the time set by the TRIGger:A:PULSEWidth:WIDth command.
EQUal argument sets the oscilloscope to trigger if a pulse is detected with width
equal to the time period specified in TRIGger:A:PULSEWidth:WIDth within
a ±5% tolerance.
NOTEQual argument sets the oscilloscope to trigger if a pulse is detected with
width greater than or less than (but not equal) the time period specified in
TRIGger:A:PULSEWidth:WIDth within a ±5% tolerance.
Examples TRIGGER:A:PULSEWIDTH:WHEN LESSTHAN specifies that the duration of the A
pulse will fall within defined high and low limits.
TRIGGER:A:PULSEWIDTH:WHEN? might return :TRIGGER:A:PULSEWIDTH:
WHEN THAN indicating the conditions for generating a width trigger.
