CUSTOM TRIGGER SETUP
1. Touch the Custom button to select Custom mode.
2. Touch inside # of Lines, and enter a value up to 1500, using the pop-up keypad.
3. Touch inside Hz and select 50 or 60 Hz from the pop-up menu.
4. Touch inside Interlace and select an interlacing factor from the pop-up menu.
Note: A selection from this menu of 1:1 will reset the # of Fields selection to 1,
since interlacing does not apply to a single field. The maximum allowable
interlace factor is equal to the # of Fields set.

HOW GLITCH TRIGGER WORKS
Glitch trigger can be used to catch glitches. You can specify a pulse width or a pulse width range.
Pulse smaller than selected pulse width: Set a maximum pulse width. This glitch trigger is generated on the
selected edge (positive or negative) when the pulse width is less than or equal to the set width.
The timing for the width is initialized and restarted on the opposite slope to that selected.
Note: If the glitch's width is narrower than the signal's width, set the trigger to a narrower width than that of the
signal. The signal's width, as determined by the instrument trigger comparator, depends on the DC trigger
level. If that level were to be set at the middle of a sine wave, for example, the width could then be considered
as the half period. But if the level were higher, the signal's width would be considered to be less than the half
period.
Glitch Trigger: In this example triggering on a pulse width less than or equal to the width selected. The broken upward-pointing
arrow indicates a potential trigger, while the bold one shows where the actual trigger occurs.
