Query Syntax

:SPRocessN:FFEQualizer:MNPRecursors?

Description

When the Linear Feed Forward Equalizer (FFE) operator is set to automatically configure the precursors (:SPRocess:FFEQualizer:NPRecursors:AUTO), this command allows you to set or query the limit for maximum number of precursors. This is equivalent to setting the Max Precursors setting in the Taps tab of the Linear Feed Forward Equalizer Setup dialog.

The default value is 3. The minimum value is 0. The maximum value is one less than the Number of Taps setting.

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:MNPRecursors 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:MNPRecursors
