(For example ... WebMar 2, 2015 · Normally I use a VBW at least with a 2:1 VBW/RBW ratio unless i am measuring continuous signals. But, just to experiment i lowered the VBW below RBW and -as expected- the transient peaks vanished slowly. So, looking at the above pictures, the "peaks" at the burst edges are exactly what is meant by the "transient effects". WebIf VBW is less than RBW, this relation for sweep time is useful: = (). Here t sweep is the sweep time, k is a dimensionless proportionality constant, f 2 − f 1 is the frequency range of the sweep, RBW is the resolution bandwidth, and VBW is the video bandwidth.
