Select the holdoff by touching the Holdoff tab, then
the Time or Events button. Using the pop-up
numeric keypad, enter a value and specify the unit of
time, or use the up/down buttons to increase or
decrease the time value in increments of 200 ps. Or,
touch one of the preset value buttons.
Standard Triggers
Edge Use Edge trigger for simple, repetitive signals. This trigger is
activated by basic waveform features or conditions such as a
positive or negative slope, and hold-off
Width Width trigger allows you to define a positive or negative-going
pulse width bounded by a voltage level, above or below where a
trigger occurs. Or you can specify a pulse width and voltage
range, in or outside where a trigger occurs.
Qualified The Qualified (A-B) trigger allows arming of the trigger on Event
A and triggering on Event B. If the arming event is a Pattern that
occurs once (Pattern) or that occurs and stays satisfied
(PatState), then the triggering event can be an Edge, Width,
Glitch, or Interval condition. This functionality is identical to
Teledyne LeCroy's previous Qualify and State triggers, but
presented in a different UI.
Pattern Pattern trigger enables triggering on a logical combination
(pattern) of five inputs: CH1, CH2, CH3, CH4, EXT. You have a
choice of four Boolean operators (AND, NAND, OR, NOR), and
you can stipulate the high or low voltage logic level for each
input independently.
TV TV triggers provide stable triggering on standard or custom
composite video signals. Use them on PAL, SECAM, or NTSC
systems. Use CUSTOM setup for other standards. Standard HDTV
trigger supports 1080i, 1080p, and 720p formats.
