:MEASure:EYE:PAM:ESKew
Command Syntax
:MEASure:EYE:PAM:ESKew
Query Syntax
:MEASure:EYE:PAM:ESKew?
Description
Returns the PAM Eye Skews measurement where the skew (seconds or UI) of an eye is measured on a PAM signal. For NRZ signals, the skew is always 0.0 seconds. Select the eye measurement to be returned using the :MEASure:EYE:PAM:ELEVel:EYE child command. To measure the eye skews for all of the eyes on a PAM signal, you must send this command once for each eye as there is no command for simultaneously measuring all eye skews.
