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.
