Commands Listed in Alphabetical Order
LOGic specifi es
that a trigger occurs when specified conditions are met and is
controlledbytheTRIGger:A:LOGIc? commands.
PULSe specifie
s that a trigger occurs when a specified pulse is found and is
controlledbytheTRIGger:A:PULse? commands.
BUS specifie
s that a trigger occurs when a communications signal is found.
Supports CAN, I
2
C, SPI, and RS232 communications signals.
VIDeo speci
fies that the trigger occurs when a video signal is found.
Examples
TRIGGER:A:TYPE EDGE sets the A trigger type to EDGE.
TRIGGER:A:TYPE? might return :TRIGGE R:A:TYPE PULSE indicating that the
A trigger type is a pulse trigger.
TRIGger:A:UPPerthreshold:CH<x>
Sets the upper threshold for channel <x>, where x is the channel number. Each
channel can have an independent level. Used only for runt and slew rate trigger
types.

Syntax
TRIGger:A:UPPerthreshold: CH<x> {<NR3>|ECL|TTL}
TRIGger:A:UPPerthreshold: CH<x>?
Arguments
<NR3> is the threshold level in volts.
ECL specifies a preset ECL high level of –1.3 V.
TTL specifies a preset TT L high level of 1.4 V.
Examples
TRIGGER:A:UPPERTHRESHOLD: CH2 50E-3 sets the upper limit of the pulse
runt trigger to 50 mV for channel 2.
TRIGGER:A:UPPERTHRESHOLD: CH2? might return :T RIGGER:A:
UPPERTHRESHOLD:CH2 1.2000E-01
indicating that the upper limit of the pulse
runt trigger is set to 120 mV.
TRIGger:A:VIDeo? (Query Only)
Returns the A trigger video parameters.
