24–40 GHz SPECTRUM COMPACT v.2 (FW V5.3.3)

OPERATION

2.6

RBW & VBW

The RBW & VBW menu allows selecting the resolution bandwidth (RBW) and video

bandwidth (VBW) of the spectrum analyzer.

The available RBW values are:



100 kHz



300 kHz



1 MHz

Narrower RBW allows to distinguish closer signals, but the span is swept
considerably slower.

The minimum allowed SPAN differs for each of the resolution bandwidths - 10
MHz for 100 kHz RBW, 30 MHz for 300 kHz RBW and 100 MHz for 1 MHz RBW.
