    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.
