Tektronix MDO4000B Series User Manual

Commands Listed in Alphabetical Order
Examples
TRIGGER:B:LEV
EL TTL
sets the B trigger level to 1.4 V.
TRIGGER:B:LEVEL? might return :TRIGGER:B:LEVEL 173.0000E-03
indicating that the B trigger level is currently set at 173 mV.
TRIGger:B:LEVel:CH<x>
This command specifies the B trigger level for channel <x>, where x is the
channel number. Each Channel can have an independent Level.
Group
Trigger
Syntax
TRIGger:B:LEVel:CH<x> {ECL|TTL|<NR3>}
TRIGger:B: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 a floating point number that specifies the trigger level in user units
(usually volts).
Examples
TRIGGER:B:LEVEL:CH2? might return :TRIGGER:B:LEVE L:CH2
1.3000E+00
indicating that the B edge trigger is set to 1.3 V for channel 2.
TRIGGER:B:LEVEL:CH3 TTL sets the B edge trigger to TTL high level for
channel 3.
TRIGger:B:LEVel:D<x>
This command specifies the B trigger level for digital channel <x>, where x isthe
channel number. Each chann
el can have an independent level.
NOTE. MDO3000 models only have two digital threshold controls: one for digital
channels D0 - D7, and the o ther for D8 - D15. Digital channel trigger levels
cannot be set independently for these models. Changing one digital channel’s
threshold l evel changes all of the channels’ levels in the same set.
