:FUNCtion:PARameters:DFEQualizer:BWMode

DFE Parameters Commands

Command Syntax

:FUNCtionN:PARameters:DFEQualizer:BWMode {CUSTom | TSBandwidth}

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

:FUNCtionN:PARameters:DFEQualizer:BWMode?

Query Response

{CUST | TSB}

Description

Chooses how you want to specify the bandwidth of the low-pass filter that is applied to the DFE threshold waveform prior to summing it to the unequalized waveform:

  • CUST — You enter the custom low-pass filter bandwidth manually using the :FUNCtion:PARameters:DFEQualizer:BANDwidth command.
  • TSBandwidth — The low-pass filter bandwidth tracks the source bandwidth. The low-pass filter bandwidth is 0.75 times the Nyquist bandwidth of the source.
