OCBW Measurement

Overview

Background

OCBW (OCcupied BandWidth) refers to the bandwidth
of the channel that consumes (occupies) the specified
amount of power.

Parameter Channel

bandwidth

The frequency bandwidth that the
target channel occupies.
0kHz to Current span

Channel

space

The frequency distance between each
main channel.
0kHz to 3GHz

OCBW

The ratio of occupied bandwidth as
the amount of power consumed.
0% to 100%, 0.1% resolution

OCBW measurement step

1. Activate OCBW
