TRIGGER:A:RUN
T:WHEN MORETHAN
sets the runt trigger to occur when the
oscilloscope detects a runt in a pulse wider than the specified width.
TRIGGER:A:RU
NT:WHEN?
might return :TRIGGER:A:PULSE:RUNT:WHEN
OCCURS
indicating that a runt trigger will occur if the oscilloscope detects a runt
of any detectable width.
TRIGger:A:
RUNT:WIDth
This command specifies the width, in seconds, for a runt trigger.
To set the trigger voltage threshold level for the edge, pulse width, runt,
or transition (rise/fall or slew rate) trigger, use TRIGger:A:LEVel:AUXin,
TRIGger:A:LEVel:CH<x>,orTRIGger:A:LEVel:D<x>.

TRIGger:A:RUNT:WHEn
Arguments
<NR3> is a floating point number that specifies the minimum width, in seconds.
Examples
TRIGGER:A:RUNT:WIDTH 15E-6 sets the minimum width of the pulse runt
trigger to 15 µs.
TRIGGER:A:RUNT:WIDTH? might return :TRI GGER:A:PULSE:RUNT:WIDTH
2.0000E-09
indicating that the minimum width of a pulse runt trigger is 2 ns.
TRIGger:A:SETHold? (Query Only)
Returns the clock edge polarity, voltage threshold and source input; data voltage
threshold and source; and both setup and hold times for setup and hold violation
triggering.

Trigger
Syntax
TRIGger:A:SETHold:CLOCk:EDGE {FALL|RISe}
TRIGger:A:SETHold:CLOCk:EDGE?
Arguments
FALL specifies polarity as the clock falling edge.
RISe specifies polarity as the clock rising edge.
Examples
TRIGGER:A:SETHOLD:CLOCK:EDGE RISE specifies the polarity as the clock
rising edge.
TRIGGER:A:SETHOLD:CLOCK:EDGE? might return :TRIGGER:A:SETHOLD:
CLOCK:EDGE RISE
indicating that polarity is specified as the clock rising edge.

Related Commands
TRIGger:A:SETHold:DATa:SOUrce
Arguments
CH1–CH4 specifies the analog channel to use as the clock source waveform.
D0–D15 specifies the digital channel to use as the clock source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
AUX specifies an external trigger using the Aux In connector located on the front
panel of the oscilloscope. (For MSO/DPO 4000B series models, MDO4000C
series models without an RF option, and 2-channel MDO3000 models only.)
Examples
TRIGGER:A:SETHOLD:CLOCK:SOURCE CH1 specifies channel 1 as the clock
source for a setup and hold trigger operation.
TRIGGER:A:SETHOLD:CLOCK:SOURCE? might return :TRIGGER:A:SETHOLD:
CLOCK:SOURCE CH4
indicating that channel 4 is the clock source for a setup and
hold trigger operation.
