TRIGger:A:TI
MEOut:SOUrce
When triggering using the TIMEOut trigger type, this command specifies the
source. The available sources are live channels, the digital channels, theAux
Input connec
tor (MSO/DPO 4000B series models, MDO4000C series models
without an RF option, and 2-channel MDO3000 models), or RF power level
(MDO4000/B/C only). The default is channel 1. The timeout trigger type is
selected using TRIGger:A:PULse:CLAss TIMEOut.

TRIGger:A:TIMEOut:TIMe
TRIGger:A:TIMEOut:POLarity
TRIGger:A:PULse:CLAss
Arguments
CH1–4 specifies an analog channel as the timeout trigger source.
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.)
LINE specifies the AC line as the timeout trigger source.
D0–D15 specifies a digital channel as the timeout trigger source.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
RF specifies that the internal RF power level can be used as the timeout trigger
source. (MDO4000/B/C models only, and requires installation of an MDO4TRIG
application module.)
Examples
TRIGger:A:TIMEOut:SOUrce CH4 specifies to use channel 4 as the source
for the timeout trigger.
TRIGger:A:TIMEOut:SOUrce? might return CH1, indicating that channel 1 has
been set as the source for the timeout trigger.

TRIGger:A:TI
MEOut:TIMe
When triggering using the TIMEOut trigger type, this command specifies the
timeout time, in seconds. The default and minimum is 4.0E-9 seconds and the
maximum is 8.
0 seconds. The resolution is 800.0E-12 which means that the
increments of time specified is 800 picoseconds. The timeout trigger type is
selected using TRIGger:A:PULse:CLAss TIMEOut

Arguments
<NR3> is a floating point number that specifies the timeout time, in seconds.
Examples
:TRIGger:A:TIMEOut:TIMe 4.0E-9 specifies the timeout time of 4.0 nsec.
:TRIGger:A:TIMEOut:TIMe? might return 8.0000E-9, which is the default.

for the transition trigger.
Group
Trigger
Syntax
TRIGger:A{:TRANsition|:RISEFall}:DELTatime <NR3>
TRIGger:A{:TRANsition|:RISEFall}:DELTatime?
Arguments
<NR3> is a floating point number that specifies the delta time, in seconds.
Examples
TRIGGER:A:TRANSITION:DELTATIME 15E-6 sets the delta time of the
transition trigger to 15 µs.
TRIGGER:A:TRANSITION:DELTATIME? might return :TRIGGER:A
:TRANSITION:DELTATIME 2.0000E-09
indicating that the delta time of the
transition trigger is set to 2 ns.
TRIGger:A{:TRANsition|:RISEFall}:POLarity
This command specifies the polarity for the transition trigger.
Group
Trigger
Syntax
TRIGger:A{:TRANsition|:RISEFall}:POLarity
{EITher|NEGative|POSitive}
TRIGger:A{:TRANsition|:RISEFall}:POLarity?
Arguments
POSitive indicates that a pulse edge must traverse from the lower (most
negative) to higher (most positive) level for transition triggering to occur.
NEGative indicates that a pulse edge must traverse from the upper (most positive)
to lower (most negative) level for transition triggering to occur.
EITher indicates either positive or negative polarity.
Examples
TRIGGER:A:TRANSITION:POLARITY NEGATIVE sets the transition polarity to
negative.
