Query Syntax

:SPRocessN:DFEQualizer:CLKDelay?

Description

Sets the time delay for a Decision Feedback Equalizer operator (DFE), which delays the decision point used by the slicer. The decision point is placed directly between the edges, so as to delay the edges.

For Reference Rx operator, what function do I send this command to?

If the DFE equalizer is a secondary function to the Reference Rx operator, address the :SPRocess:DFEQualizer:CLKDelay command to the Reference Rx function as identified in the following Reference Rx Setup dialog's operator diagram. In the following figure, this would be Function 2 and the command would be:

:SPRocess2:DFEQualizer:CLKDelay
