A spectrum analyzer can EASILY provide 90dB of dynamic range, if not more. So, this is the big difference between an oscilloscope running an FFT and spectrum analyzer: Dynamic range.

This spectrum analyzer capability, still in the concept phase, is expected to work through a portable, tablet-like piece of equipment, with sensors at tactical operations centers or mounted on ...

The peer-reviewed journal Physical Review Applied published the researchers’ findings, Waveguide-coupled Rydberg spectrum analyzer from 0 to 20 GigaHerz, co-authored by Army researchers Drs ...

In the portable spectrum analyzer of Figure 1, the MSMXVHF includes a switching mixer that functions up to 600 MHz. The output of the mixer is limited to 1 MHz by a second-order, continuous-time ...
