Trigger Modes
Edge – Positive 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 1.0 ns with
200 ps resolution.
Width – Trigger on width of positive or negative pulse
either within or out of selectable time limits (1 ns to 1 s).
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 1 ns
to 1 s with 200 ps resolution.
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.
Trigger Delay by Time – 16 ns to 250 seconds.
Trigger Delay by Events – 1 to 10,000,000 Events.
