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:
MEASurement<m>:JITTer:DRUNit on page 2259
18.1.2.4 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.
See also: Table 18-1
► To configure a measurement, tap it in the "Active Measurements" list.
Source 1, Source 2
"Source 1" is the reference signal, and "Source 2" is the signal compared to the refer-
ence signal.
Skew delay =

Source1
for k = 1,...,K
Edge polarity
Sets the edge of the first waveform from which the skew delay or phase is measured:
positive, negative or both.
Remote command:
MEASurement<m>:JITTer:SKWSlope on page 2260
Relative polarity
Sets the edge of the second waveform relative to the first waveform.
"Matching"
Measures from positive to positive edge or from negative to negative
edge.
"Inverse"
Measures from positive to negative edge or from negative to positive
edge.
Remote command:
MEASurement<m>:JITTer:SKWRelation on page 2260
