Making Basic Measurements Using Spectrum Analyzer Mode

Resolving Small Signals Hidden by large Signals Using the Resolution Bandwidth Function

4.Set the 300 MHz signal to the reference level by pressing (jj], then MARKER 4REF LVL .

(PEAK SEARCH_),

If a 10 kHz filter with a typical shape factor of 15: 1 is used, the filter will have a bandwidth of 150 kHz at the 60 dB point. The half-bandwidth (75 kHz) is narrower than the frequency separation, so the input signals will be resolved.
