Commands listed in alphabetical order
Syntax
TRIGger:{A|B}:PULSEWidth:POLarity {NEGative|POSitive}
TRIGger:{A|B}:PULSEWidth:POLarity?
Arguments
NEGative
speci fi es a negative pulse.
POSitive
speci fi es a positive pulse.
Examples
TRIGger:A:PULSEWidth:POLarity NEGATIVE
sets the pulse polarity to
negative.
TRIGger:A:PULSEWidth:POLarity?
might return
:TRIGGER:A:WIDTH:POLARITY POSITIVE
indicating a positive pulse.
TRIGger:{A|B}:PULSEWidth:SOUrce
This command speci fi es the source waveform for a pulse width trigger.
Group Trigger
Syntax
TRIGger:{A|B}:PULSEWidth:SOUrce {CH<x>|CH<x>_D<y>}
TRIGger:{A|B}:PULSEWidth:SOUrce?
Arguments
CH<x>
speci fi es an analog input channel as the pulse-width trigger source.
CH<x>_D,y>
speci fi es an digital input channel as the pulse-width trigger source.
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 trigger source.
TRIGger:{A|B}:PULSEWidth:WHEn
This command speci fi es to trigger when a pulse is detected with a width (duration)
that is less than, greater than, equal to, or unequal to a speci fi ed value (set using
TRIGger:{A|B}:PULSEWidth:LOWLimit ), OR whose width falls outside of or
within a speci fi ed range of two values (set using TRIGger:{A|B}:PULSEWidth:
LOWLimit and TRIGger:{A|B}:PULSEWidth:HIGHLimit ).
