After selecting the centre frequency, users can set the channel BW by
inputting the frequency manually. The default channel BW is 8MHz. In order
to measure accurately, the span frequency is set to 1.5 times of the channel
BW.
Press the channel BW soft-key to change the value. The default value is
8MHz. Channel bandwidth is proportional to span. Therefore, span will be
changed according to channel BW value. The channel bandwidth can also
be changed by digital inputs, up/down key and knob.
