Skew Adjustment
You can modify the skew or timing deviation between modules within the intermodule measurement. This allows you to compensate for any known delay of the system under test, or to compare two signals by first removing any displayed skew between the signal channels.
Skew adjustments can correct module delays to within 2 ns of other modules. Note that the module or channel that is used as the trigger is normally the reference channel, and adjustments are normally made to deskew the nonreference channels.
