Characteristic
Description
Pulse-type runt trigger sensitivity,
typical
0.75 division from DC to maximum bandwidth
Aux In does not support Pulse trigger
Pulse-type trigger width sensitivity,
typical
3.5 ns when only using digital channels D0-D7
4.5 ns when using any of the digital channels D8-D15
Aux In does not support Pulse trigger

For Logic, time between channels refers to the length of time a logic state derived from
more than one channel must exist to be recognized. For Events, the time is the minimum time
between a main and delayed event that will be recognized if more than one channel is used.

Setup/hold violation trigger, setup
and hold time ranges
Input coupling on clock and data channels must be the same.
For Setup time, positive numbers mean a data transition before the clock.
For Hold time, positive numbers mean a data transition after the clock edge.
Setup + Hold time is the algebraic sum of the Setup Time and the Hold Time programmed by
the user.

For the trigger class width and the trigger class runt, the pulse width refers to the width of the
pulse being measured. The rearm time refers to the time between pulses.
For the trigger class Rise/Fall time, the pulse width refers to the delta time being measured.
The rearm time refers to the time it takes the signal to cross the two trigger thresholds again.
