Setup/Hold time measurement
Setup/Hold measurements analyze the relative timing between two signals: a data sig-
nal and the synchronous clock signal. Setup time is the time that the data signal is
steady before clock edge - the time between a data transition and the next specified
clock edge. Hold time is the time that the data signal is steady after clock edge - the
time between a data transition and the previous specified clock edge.
"Setup/Hold time" measures and displays the setup and hold durations. "Setup/Hold
ratio" measurements return the ratio of the setup time to the sum of hold and setup
time: T

The clock edge can be defined, the polarity of the data signal does not matter.
