Trigger Types

Edge –
Positive and/or negative slope on any channel or
front panel auxiliary input. Coupling includes DC,
AC, noise reject, HF reject and LF reject.
Glitch –
Trigger on or reject glitches of positive, negative
or either polarity. Minimum glitch width is down
to 100 ps with re-arm time of 250 ps.
Width –
Trigger on width of positive or negative pulse
(down to 100 ps) either within or out of selectable
time limits.
Runt –
Trigger on a pulse that crosses one threshold but
fails to cross a second threshold before crossing
the first again. Optional time qualification.
Timeout –
Trigger on an event which remains high, low or
either for a specified time period, selectable from
360 ps to 1 s.
Transition –
Trigger on pulse edge rates that are faster or
slower than specified. Slope may be positive,
negative or either.
Setup/Hold –
Trigger on violations of both setup time and hold
time between clock and data present on any two
input channels.
Pattern –
Trigger when pattern goes false or stays true for
specified period of time. Pattern (AND, OR, NAND,
NOR) specified for four input channels defined as
HIGH, LOW or Don’t Care.
State –
Any logical pattern of channels (1, 2, 3) clocked
by edge on channel 4. Trigger on rising or falling
clock edge.
Window –
Trigger on an event that enters or exits a window
defined by two user-adjustable thresholds. Event can
be time or logic qualified.
Trigger Delay by Time – 5 ns to 250 seconds.
Trigger Delay by Events – 1 to 10,000,000 events.
