Ref level
The setting defines the "Data ref level" for setup and hold measurements, and for time-
interval error measurements (option R&S
RTO6-K12). It selects the reference level of
the data signal on which the time is measured. The intersection of slope and reference
level defines the time point for measurements.
For clock jitter measurements (option R&S
RTO6-K12), it sets the "Reference level" for
the time measurement.
Remote command:
MEASurement<m>:AMPTime:DATA<n>:LSELect
Unit
Sets the unit to bps (bit per second), or to Hz for analysis of radar signals. The setting
is available for data rate measurements.
Remote command:

Delay measurement settings
Skew delay and skew phase measurements are intended to measure the time differ-
ence between the edges of two waveforms. The measurements are simplified variants
of the "Delay" and "Phase" measurements assuming that both sources are similar
except for the delay.

Source 1, Source 2
"Source 1" is the reference signal, and "Source 2" is the signal compared to the refer-
ence signal.

Edge polarity
Sets the edge of the first waveform from which the skew delay or phase is measured:
positive, negative or both.
