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

TRIGger:A:PULse:CLAss
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.
TRIGger:A{:TRANsition|:RISEFall}? (Query Only)
Returns transition time trigger parameters.

TRIGger:A{:T
RANsition|:RISEFall}:DELTatime
This command specifies the delta time used in calculating the transition value
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.

TRIGGER:A:TRA
NSITION:POLARITY?
might return :TRIGGER:A:
TRANSITION:POLARITY EITHER
indicating that the polarity can be either
positive or negative.
TRIGger:A{:TRANsition|:RISEFall}:SOUrce
This command specifies the source for a transition trigger.
Group
Trigger
Syntax
TRIGger:A{:TRANsition|:RISEFall}:SOUrce {CH1|CH2|CH3|CH4}
TRIGger:A{:TRANsition|:RISEFall}:SOUrce?
Arguments
CH1–CH4 specifies one of the analog channels to be used as the source for a
transition trigger.
Examples
TRIGGER:A:TRANSITION:SOURCE CH4 sets channel 4 as the source for the
transition trigger.
TRIGGER:A:TRANSITION:SOURCE? might return :TRIGGER:A:TRANSITION:
SOURCE CH2
indicating that channel 2 is the source for the transition trigger.
TRIGger:A{:TRANsition|:RISEFall}:WHEn
This command specifies whether to check for a transitioning signal that is faster or
slower than the specified delta time.
Group
Trigger
Syntax
TRIGger:A{:TRANsition|:RISEFall}:WHEn
{SLOWer|FASTer|EQual|UNEQual}
TRIGger:A{:TRANsition|:RISEFall}:WHEn?
Arguments
FASTer sets the trigger to occur when the signal transition time is faster than the
time set by
TRIGger:A:TRANsition:DELTatime.
SLOWer sets the trigger to occur when the signal transition time is slower than the
time set by.
TRIGger:A:TRANsition:DELTatime.
EQual sets the trigger to occur when the signal transition time is equal to the time
set by
TRIGger:A:TRANsition:DELTatime.
