Feature Min Max
Setup time
–0.5 ns 1.0 ms
Hold time 1 ns 1.0 ms
Setup + Hold tim e
0.5 ns 2.0 ms
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 H old time, positive numbers mean a data transition after the clock edge.
Setup + Hold time is the algebraic sum of the Setup Time and Hold Time that you
programmed.
Pulse class Minimum

2 ns + 5% of glitch width setting
Runt 4 ns 2 ns
Time-qualified runt

Slew rate (transition time)

Pulse type trigger, minimum pulse,
rearm tim e, transition time
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 slew rate, 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.
Transition time trigger, delta time
range

Time range for glitch, pulse width,
timeout, time-qualified runt, or
time-qualified window triggering
4nsto8s
Time Range Accuracy
1 ns to 500 ns
±(20% of setting + 0.5 ns)
Time Accuracy for Pulse, Glitch,
Timeout, or Width Triggering
520 ns to 1 s
±(0.01% of setting + 100 ns)
B trigger after events, minimum
pulse width and maximum event
frequency, typical
4 ns, 500 MHz
B trigger, minimum time between
arm and trigger, typical
4ns
For trigger after time, this is the time between the end of the time period and the B trigger
event.
For trigger after events, this is the time between the last A trigger event and the first B trigger
event.
B trigger after time, time range
4nsto8seconds
B trigger after events, event range
1 to 4,000,000
