Skew Measurement
The skew measurement allows you to compare the step responses calculated from dif-
ferent traces measured on the same analyzer channel. The skew is calculated as the
"delta time" (or length) at user defined percentage of the step size.

For instance, this can be used to evaluate the quality of a balanced transmission line
("intra-pair skew").
Limit Test
Testing against a user-defined skew limit is also supported.
DUT-centric setup
As far as possible the required settings are related to time domain properties of the
DUT, which might be more intuitive for users of digital oscilloscopes that are not famil-
iar with vector network analyzers.
The Automatic Harmonic Grid from the option R&S ZNB/ZNBT-K2 "Time domain
Analysis" is used to ease setting up the frequency grid for all measurements provided
by the option R&S ZNB/ZNBT-K20.
