:FUNCtion:PARameters:FFEQualizer:BWMode?

Description

The linear Bandwidth Mode control lets you minimize noise gain by rolling off the response above the frequency where there is mostly just noise:

  • CUSTom — If you know at what frequency you want the response to roll off, you can enter it manually using the :FUNCtion:PARameters:FFEQualizer:BANDwidth command.
  • TSBandwidth — (Track Source Bandwidth, default) This option simply generates a response up to the bandwidth of the source. For example, if your source is channel 1 and its bandwidth is set to 12 GHz, the response will go to 12 GHz before rolling off. This is the method that maximizes the noise gain.
  • TTSpacing — (Track Tap Spacing) This option forces the response to roll off at a typical ratio of bandwidth to data rate (0.75 x data rate). This will minimize the noise and is best used if you are unsure where in the frequency spectrum the noise is the dominant factor, but would like to minimize the noise gain.
