Commands Listed in Alphabetical Order
Arguments <NR3> specifies the trigger level, in volts.
ECL specifies a preset ECL trigger level of –1.3V.
TTL specifies a preset TTL trigger level of 1.4V.
Examples TRIGGER:A:LEVEL:AUXIN ECL sets the auxiliary input trigger level to -1.3
volts.

Sets or returns the trigger level for the specified channel. Each channel can have
an independent level.
Group Trigger
Syntax TRIGger:A:LEVel:CH<x> {<NR3>|TTL|ECL}
TRIGger:A:LEVel:CH<x>?
Arguments <NR3> specifies the trigger level in user units (usually volts).
TTL specifies a preset TTL high level of 1.4V.
ECL specifies a preset ECL high level of –1.3V.
Examples TRIGGER:A:LEVEL:CH2? might return :TRIGGER:A:LEVEL:CH2
1.3000E+00 indicating that the A edge trigger is set to 1.3 V for channel 2.
TRIGGER:A:LEVEL:CH3 TTL sets the A edge trigger to TTL high level for
channel 3.
TRIGger:A:LEVel:D<x>
Sets or returns the trigger level for the specified digital channel <x>, where x is
the channel number. Each digital channel can have an independent level.
