Tektronix TBS2000 Series User Manual

Arguments
<NR3> is the A trigger holdoff time. The range is 20 ns to 8.0 s.
Examples
TRIGger:A:HOLDOff:TIMe10 sets the holdoff time to 10 s.
TRIGGER:A:HOLDOFF:TIME? might return :TRIGGER:A:HOLDOFF:TIME
1.2000E-06 indicating that the A trigger holdoff time is set to 1.2 μs.
TRIGger:A:LEVel
Sets or queries the trigger level for the A trigger. This command is equivalent to
adjusting the front-panel TRIGGER LEVEL knob.
NOTE. When the edge trigger source is set to AC LINE, the instrument ignores
the set form of the command.
When the edge trigger source is set to AC LINE, the query form of the command
returns zero.
Group
Trigger
Syntax
TRIGger:A:LEVel{ECL|TTL|<NR3>}
TRIGger:A:LEVel?
Arguments
<NR3> specifies the trigger level in user units (usually volts).
ECL specifies a preset ECL high level of -1.3V.
TTL specifies a preset TTL high level of 1.4V.
Examples
TRIGGER:A:LEVEL TTL sets the A edge trigger to TTL high level, which is
1.4 V.
TRIGger:A:LEVel? might return :TRIGGER:A:LEVel 1.3000E+00 indicating
that the A edge trigger is set to 1.3 V.
