3.2.2 Basic Parameters Settings

The basic parameters refer to the RBW, VBW, video average, sweep mode,
sweep time, trig mode and etc. of the device. This part is mainly used to set
the parameters of the medium frequency receipt unit of the spectrum
analyzer.
The basic parameter is set with the CPL key. It is at the upper right corner
of the operation panel.
Press the soft-key, and the following menu would pop up.
1 BW Settings
(1) RBW
Resolution bandwidth (RBW) refers to the IF filter bandwidth of the
spectrum analyzer. RBW defines the smallest frequency difference of two
adjacent signals that can be distinguished by the spectrum analyzer. So the
narrower the RBW is set, the higher precision the spectrum has. But it
needs more establish time with narrow RBW. If the sweep time cannot
fulfill the requirement of RBW, the system will give the prompt 'UNCAL'.
