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 (PEAK SEARCH_),
(jj], then MARKER 4REF LVL .
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.
