Commands Listed in Alphabetical Order
TRIGger:A:LOWerthreshold:CH<x>Sets or returns the lower threshold for the channel selected. Each channel can
have an independent level. Used in Runt and Slew Rate triggers as the lower
threshold. Used for all other trigger types as the single level/threshold.
Group Trigger
Syntax TRIGger:A:LOWerthreshold:CH<x> {ECL|TTL|<NR3>}
TRIGger:A:LOWerthreshold:CH<x>?
Related Commands TRIGger:A:LEVel:CH<x>
Arguments ECL specifies a preset ECL high level of –1.3V.
TTL specifies a preset TTL high level of 1.4V.
<NR3> is the clock level, in volts.
Examples TRIGGER:A:LOWERTHRESHOLD:CH2 50E-3 sets the lower limit threshold for
CH2ofthepulserunttriggerto50mV.
TRIGGER:A:LOWERTHRESHOLD:CH2? might return :TRIGGER:A:
LOWERTHRESHOLD:CH2 1.2000E-01 indicating that the lower limit threshold
for CH2 of the pulse runt trigger is set to 120 mV.
TRIGger:A:LOWerthreshold:D<x>Sets the lower threshold for the digital channel selected. Each channel can have
an independent level. Used in runt and slew rate as the lower threshold. Used for
all other trigger types as the single level/threshold.
Group Trigger

TRIGger:A:LOWerthreshold:D<x>?
Arguments <NR3> specifies the threshold voltage, in volts.
