Trigger Setup
Trigger Type Trigger Conditions
Setup and Hold Trigger when a logic data input changes state inside of the
setup or hold time relative to a clock edge.
Setup is the amount of time that data should be stable and
not change before a clock edge occurs. Hold is the time
that data should be stable and not change after a clock
edge occurs.
Use the
Clock side-bezel button to select the clock
channel. Use the Select control, Data , and Not used
buttons to select one or more channels you want to monitor
for setup and hold violations.
NOTE. Optimum Setup and Hold trigger performance
is achieved by using only analog channels or only digital
channels.
Rise/Fall Time Trigger on rise and fall times. Trigger on pulse edges that
traverse between two thresholds at faster or slower rates
than the speci
fi ed time. Specify pulse edges as positive,
negative, or either.
