Commands Listed in Alphabetical Order
Arguments
ECL specifies a p
reset ECL high level of –1.3V.
TTL specifies a preset TTL high level of 1.4V.
<NR3> is a floating point number that specifies the trigger level in user units
(usually volts).
TRIGger:B:LOWerthreshold:CH<x>
This command specifies the B trigger lower threshold for the channel <x>, where
x is the channel number. Each channel can have an independent level. Used in
runt and transition triggers as the lower threshold. Used for all other trigger types
as the single level/threshold.

Syntax
TRIGger:B:LOWerthreshold:CH<x> {ECL|TTL|<NR3>}
TRIGger:B:LOWerthreshold: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 a floating point number that specifies the threshold level, in volts.
TRIGger:B:LOWerthreshold:D<x>
Sets or queries the lower threshold for the digital channel selected. Each channel
can have an independent level. Used in runt and transition triggers as the lower
threshold. Used for all other trigger types as the single level/threshold.
NOTE. MDO3000 models only have two di
gital threshold controls: one for digital
channels D0 - D7, and the other for D8 - D15. Digital channel trigger levels
cannot be set independently for these models. Changing one digital channel’s
threshold level changes all of the channels’ levels in the same set.
