TRIGger[:SEQuence]:LEVel:VIDeo <Level>
This command defines the level the video signal must exceed to cause a trigger event.
Note that any RF attenuation or preamplification is considered when the trigger level is
analyzed.
Parameters:
<Level> Range: 0 PCT to 100 PCT
*RST: 50 PCT
Example: TRIG:LEV:VID 50PCT
Manual operation: See "Trigger Level" on page 430
TRIGger[:SEQuence]:SLOPe <Type>
For all trigger sources except time you can define whether triggering occurs when the
signal rises to the trigger level or falls down to it.
For external and time domain trigger sources you can define whether triggering occurs
when the signal rises to the trigger level or falls down to it.
Parameters:
<Type> POSitive | NEGative
POSitive
Triggers when the signal rises to the trigger level (rising edge).
NEGative
Triggers when the signal drops to the trigger level (falling edge).
*RST:
POSitive
Example: TRIG:SLOP NEG
Manual operation: See "Slope" on page 432
TRIGger[:SEQuence]:SOURce <Source>
This command selects the trigger source.
For details on trigger sources see "Trigger Source" on page 427.
Using a trigger or gated measurements turns the squelch off (see

on page 966).
Note on external triggers:
If a measurement is configured to wait for an external trigger signal in a remote control
program, remote control is blocked until the trigger is received and the program can
continue. Make sure this situation is avoided in your remote control programs.
For troubleshooting tips see "Uncompleted sequential commands - blocked remote
channels" on page 1103.
