Description

Turns on and off automatic configuration of taps for a Decision Feedback Equalizer operator (DFE) (:FUNCtion:FOPerator DFEQualizer). By default, automatic configuration is on.

OFF
Disables automatic tap configuration to enable manual entry of tap values. Use the :SPRocess:DFEQualizer:TAPS command to enter the individual tap values.
ON
Enables automatic tap configuration which sets the optimum tap values to open an eye diagram. This is the default setting. To enter the number of taps, use the :SPRocess:DFEQualizer:TAPS:COUNt command. Use the :SPRocess:DFEQualizer:TAPS:RECalculate command to automatically recalculate the tap values.

The Decision Feedback Equalizer operator is provided with the 86100D-201/N1010A-201 Advanced Waveform Analysis license.

Beginning with FlexDCA revision A.05.60, use of an *OPC? query to pause program execution while waiting for this command to execute.

Requires FlexDCA revision A.02.00 and above.
