Commands Listed in Alphabetical Order
Syntax
TRIGger:A:RUN
T:SOUrce { CH1|CH2|CH3|CH4|RF}
TRIGger:A:RUNT:SOUrce?
Arguments
CH1–CH4 specifies the analog channel number to use as the source
waveform for the runt trigger. To specify the threshold levels when using
CH1–CH4 as the source, use TRIGger:A:LOWerthreshold:CH<x> and
TRIGger:A:UPPerthreshold:CH<x>.
RF specifies the internal RF power level as the source (MDO4000/B/C models
only, and requires installation of an MDO4TRIG application module.) To
specify the threshold levels when using RF power level as the source, use
TRIGger:A:LOWerthreshold:RF and TRIGger:A:UPPerthreshold:RF.
Examples
TRIGGER:A:RUNT:SOURCE CH4 sets channel 4 as the trigger source.
TRIGGER:A:RUNT:SOURCE? might return : TRIGGER:A:RUNT:SOURCE CH2
indicating that channel 2 is the trigger source.
TRIGger:A:RUNT:WHEn
This command specifies the type of pulse width the trigger checks for when
it detects a runt.

Syntax
TRIGger:A:RUNT:WHEn {LESSthan|MOREthan|EQual|UN EQual|OCCURS}
TRIGger:A:RUNT:WHEn?
Related Commands
TRIGger:A:RUNT:WIDth
Arguments
OCCURS argument specifies a trigger event if a runt of any detectable width occurs.
LESSthan argument sets the oscilloscope to trigger if the a runt pulse is detected
with width less than the time set by the TRIGger:A:RUNT:WIDth command.
MOREthan argument sets the oscilloscope to trigger if the a runt pulse is detected
with width greater than the time set by the TRIGger:A:RUNT:WIDth command.
EQual argument sets the oscilloscope to trigger if a runt pulse is detected with
width equal to the time period specified in TRIGger:A:RUNT:WIDth within
a ±5% tolerance.
NOTEQual argument sets the oscilloscope to trigger if a runt pulse is detected with
width greater than or less than (but not equal to) the time period specified in
TRIGger:A:RUNT:WIDth within a ±5% tolerance.
