Command Syntax
:SPRocessN:DFEQualizer:BANDwidth <bandwidth>
<bandwidth> 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.
Query Syntax
:SPRocessN:DFEQualizer:BANDwidth?
Description
Specifies the bandwidth in Hertz of a Gaussian filter for the Decision Feedback Equalizer operator (DFE) (:FUNCtion:FOPerator DFEQualizer). The Gaussian filter defaults to the symbol rate but can be manually set up to 1 THz.
The Decision Feedback Equalizer operator is provided with the 86100D-201/N1010A-201 Advanced Waveform Analysis license.
Requires FlexDCA revision A.02.00 and above.
