In this chapter the detailed information of operation is introduced.
8.1 Main Functions
8.1.1 Frequency Functions
There are two methods to set the measuring frequency, Center/Span and Start/Stop. Span
means the measuring bandwidth. Center and Span are usually used in the situation that the
frequency under test is known. Start and Stop are used for the measured frequency of a specific
range.
Step and Peak to Center are functions to make easy operation in some case. When the step is
defined, the frequency entry will change for the step number. Peak to Center will find the peak
signal on display and then change the center frequency to the frequency of peak signal. Peak to
Center will not activate the marker.
