Video Bandwidth (VBW)
(–3 dB)
Range 30 Hz to 1 MHz in 1-3-10
sequence
3 MHz, characteristic
(Option 1DR) Adds 1, 3, 10 Hz for RBW’s
<1 kHz
Accuracy ±30%, characteristic
Shape Post detection, single pole low-
pass filter used to average
displayed noise
Video bandwidths below 30 Hz
are digital bandwidths with
anti-aliasing filtering.
