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
Default unit: PCT
Example: TRIG:LEV:VID 50PCT
Manual operation: See "Trigger Level" on page 484
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.
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 486
TRIGger[:SEQuence]:SOURce <Source>
This command selects the trigger source.
For details on trigger sources see "Trigger Source" on page 482.
Using a trigger or gated measurements turns the squelch off (see
[SENSe:]DEMod:
SQUelch[:STATe]
on page 1199).
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.
If the 1.2 GHz bandwidth extension option (B1200) or the internal 2 GHz option
(B2001) is active, only an external trigger, IF power trigger, or no trigger is available.
For troubleshooting tips see "Incompleted sequential commands - blocked remote
channels" on page 1392.
