Example:
With the settings shown in the picture, the time between the second rising edge and the
third from last falling edge is measured.
"Level selec-
tion"
Selects the reference level on which the time is measured.
"Slope"
Sets the edge of each source, between which the delay is measured:
positive, negative, or either of them.
"Direction"
Selects the direction for counting slopes for each source: from the
beginning of the waveform, or from the end.
"Number"
Sets the number of the edge that is relevant for delay measurement.

Setup/Hold measurement settings
Setup/Hold measurements analyze the relative timing between two signals: a data signal
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
Setup
/ (T
Setup
+ T
Hold
).
The clock edge can be defined, the polarity of the data signal does not matter.
