"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.

Settings for delay and phase measurements (digital sources)
Delay measurement on digital channels is reduced to measure the time between two
subsequent rising or two subsequent falling edges.
The edge direction is set with Edges slope .
Setup/Hold measurement settings
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
Setup
/ (T
Setup
+ T
Hold
) .
The clock edge can be defined, the polarity of the data signal does not matter.
