Waveform Measurement
BW
Gaussian
With a PXA or Option B40, the capability for arbitrary Digital IF bandwidths is available. However, for
instruments without the Digital IF or the Option B40 or B1X, the selectable Gaussian filter bandwidths
are predetermined in the following list. There are 160 Info BWs (RBWs). They are arranged in a
24-per-decade sequence from 1 Hz through 3 MHz, plus the 4, 5, 6 and 8 MHz settings.
