:SPRocess:FFEQualizer:TSPacing:TIMe
Command Syntax
:SPRocessN:FFEQualizer:TSPacing:TIMe <seconds>
<seconds> is a double.
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.
Description
Specifies tap spacing in seconds for a Linear Equalizer operator (LFE). To select tap spacing in seconds or taps-per-bit, use the :SPRocess:FFEQualizer:TSPacing
command. This command is not valid in automatic tap configuration mode (:SPRocess:FFEQualizer:TAPS:AUTo ON
).
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:TSPacing:TIMe
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:TSPacing:TIMe
The Linear Feedforward Equalizer operator is provided with the N1010A-201 Advanced Waveform Analysis license.
