33 Trigger Commands
Advanced User Defined TV Mode and Commands
Use TV trigger mode to trigger on one of the standard television
waveforms, as described in the previous section, and to trigger on a
custom television waveform that you define. The User Defined TV trigger
lets you trigger on nonstandard TV waveforms.
User Defined TV
Trigger
Source Use the Source control to select one of the oscilloscope channels as the
trigger source.
Level Use the Level control to set the trigger voltage level.
When setting the trigger level for your waveform, it is usually best to
choose a voltage value that is just below the bottom of burst.
When you adjust the trigger level control, a horizontal dashed line with a
T on the right- hand side appears showing you where the trigger level is
with respect to your waveform. After a period of time the dashed line will
disappear. To redisplay the line, adjust the trigger level control again, or
activate the Trigger dialog. A permanent icon with arrow (either T, T
L
, or
T
H
) is also displayed on the right side of the waveform area, showing the
trigger level.
Pos or Neg Use the Pos and Neg controls to select either a positive pulse or a negative
pulse to arm the trigger circuitry.
Time > Use the Time > control to set the minimum time that the pulse must be
present to be considered a valid sync pulse.
Edge Number Use the Edge Number control to select the number of edges you want the
oscilloscope to count before triggering.
Available trigger conditioning includes HOLDoff and HYSTeresis (Noise
Reject).
UDTV Commands These commands set the conditions for the TV trigger mode using
user- defined parameters. They are used for triggering on non-standard
television waveforms, and let you define the conditions that must be met
before a trigger occurs.

Commands
Before executing the :TRIGger:ADVanced:TV:UDTV commands, set the mode
by entering:
:TRIGger:MODE ADVanced and
:TRIGger:ADVanced:MODE TV and
:TRIGger:ADVanced:TV:MODE UDTV
