Measurement Description/Result
f
Data rate Frequency of the clock signal. If no clock signal is available, it is recov-
ered by CDR. The measurement is based on the unit interval mea-
surement.
R
Clock k
= 1 / UI
k
for k = 1,...,K-1
Skew delay Delay between the edges of two interdependent waveforms. The mea-
surement is a simplified variant of the "Delay" measurement assuming
that both sources are similar except for the delay.
Skew delay = Δ t
k
= t
Source2
- t
Source1
for k = 1,...,K

Skew phase Phase difference between the edges of two waveforms.
Skew phase = Skew delay / Period * 360° = Δ t
k
/ Δ T
Period k
* 360°
Limit and margin checks are also available for jitter measurements, see Chap-
ter 8.2.12, "Limit and margin checks", on page 396. Limit and margin checks are based
on the amplitude/time measurements.
