:SPRocess:FFEQualizer:TAPS:COUNt
Command Syntax
:SPRocessN:FFEQualizer:TAPS:COUNt <count>
<count> is a int.
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
Specifies the number of taps for a Linear Equalizer operator (LFE). Increasing the number of taps in your model increases the fidelity of the filter's frequency response as compared to an ideal response. To enter the precursors, use the :SPRocess:FFEQualizer:NPRecursors command. Before you can use these commands, turn on the automatic determination of tap values (:SPRocess:FFEQualizer:TAPS:AUTo ON).
To manually enter tap values, first disable automatic tap configuration (:SPRocess:FFEQualizer:TAPS:AUTo OFF), then use the :SPRocess:FFEQualizer:TAPS command.
Beginning with FlexDCA revision A.05.60, use of an *OPC? query to pause program execution while waiting for this command to execute.
For Reference Rx operator, what function do I send this command to?
If the FFE (Linear Equalizer) equalizer is a secondary function to the Reference Rx operator, address the :SPRocess:FFEQualizer:TAPS:COUNt 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:FFEQualizer:TAPS:COUNt
The Linear Feedforward Equalizer operator is provided with the N1010A-201 Advanced Waveform Analysis license.
