Data
Clock slope = Positive Clock slope = Either
If at least one of the setup/hold measurements is selected, additional settings appear to
specify the measurement.
"Clock slope"
Sets the edge of the clock from which the setup and hold times are
measured: positive, negative, or either of them. If "Either" is selected,
the clock edges next to the data edge are considered regardless of the
clock slope.
"Clock source"
The "Clock source" is identical to the measurement "Source". It defines
the waveform used as clock in the setup/hold measurement.
"Data source"
The "Data source" is identical to the "2nd Source" of the measurement.
It sets the data signal.
"Clock ref level"
Selects the reference level of the clock on which the time is measured.
"Clock ref level" and "Clock slope" define the time point for setup and
hold measurements.
"Data ref level"
Selects the reference level of the data on which the setup and hold time
are measured.

Pulse train count
Sets the number N of positive pulses for the "Pulse train" measurement. This measure-
ment measures the duration of N positive pulses from the rising edge of the first pulse to
the falling edge of the N-th pulse.

Edges slope
Sets the edge direction to be counted: rising edges, falling edges, or both. The setting is
only relevant for edge count measurement on digital channels.
