    BANDWIDTH ANDWIDTH The BW (BandWidth) feature configures how narrow the GSP-830 can sort out different signal peaks (resolution), and how fast the display can be updated (sweep time). Averaging the waveform is also available for smoothing noise level. The resolution, sweep time, and averaging are in a trade-off relationship, so configuration should be done with care.

  • Page 96: Select Rbw (Resolution Bandwidth)

    GSP-830 User Manual Select RBW (Resolution BandWidth) RBW (Resolution Bandwidth) defines the width of the Background IF (intermediate frequency) filter that is used to separate signal peaks from one another. The narrower the RBW, the greater the capability to separate signals at close frequencies.
