8 Trigger
8.1 Trigger
8.1.2 Trigger Level
Sets the amplitude level for Trigger and Gate sources that use level triggering.
When the video signal crosses this level, with the chosen slope, the trigger occurs.
For any given Trigger, Gate, or Periodic Sync Src, the same Trigger Level is used for
the Trigger source in the Trigger menu, for the Gate source in the Gate Source
menu, and for the Periodic Sync source in the Periodic Sync Src menu.
If Video is the selected trigger source, the trigger level displays as a green horizontal
line with the label TRIG LVL just above it on the right:
If the value of trigger level is off screen low this line displays along the bottom of the
graticule. If the value of trigger level is off screen high this line displays above the
graticule but no farther above than 1.5 % of the graticule height (the same as the
trace itself). Note that the TRIG LVL label cannot display above the graticule so the
label itself stops at the top of the graticule.
For the I/Q Triggers, the I/Q reference impedance is used for converting between
power and voltage.
