Linear Equalizer Commands

Command Syntax

:SPRocessN:FFEQualizer:TAPS "tap_value, tap_value, …"

The command argument is a comma separated list of individual tap value (real numbers). This command supports the DEFault common child command.

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

:SPRocessN:FFEQualizer:TAPS?

Description

Enters a list of tap values for a Linear Equalizer operator (LFE) (:FUNCtion:FOPerator FFEQualizer). 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 :SPRocess:FFEQualizer:TAPS:AUTo command.

The Linear Feedforward 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.
