Command Syntax

:FUNCtionN:PARameters:DFEQualizer:VTAPs "tap_value, tap_value, …"

The command argument is a string of comma separated list of real numbers (individual tap values in voltage).

Where N identifies one of up to 64 possible operators {1:64} that can be defined as part of a math function. The operators are numbered in the order that they were originally added to the function.

Query Syntax

:FUNCtionN:PARameters:DFEQualizer:VTAPs?

Description

Enters a list of tap values in voltage for a Decision Feedback Equalizer operator (DFE) (:FUNCtion:FOPerator). Increasing the number of taps in your model increases the fidelity of the filter's frequency response as compared to an ideal response. To use this command, automatic tap configuration must be turned off using the :FUNCtion:PARameters:DFEQualizer:TAPS:AUTO command.
