The '''Tektronix 2784''' is a spectrum analyzer with a frequency range of 100 Hz to 40 GHz in coax, to 325 GHz with external waveguide mixers.  The minimum resolution bandwidth is 3 Hz, with a minimum span of 10 Hz, and provides measurement resolution proportional to the frequency accuracy or span.  

In addition to conventional digital storage features, non-volatile memory (NVRAM) stores up to 20 separate waveforms with their readouts and markers, for later recall for additional analysis and comparison.  Also, store up to 20 different front-panel control setups for future recall.  The instrument can selectively count one particular signal out of several that may be present at its input.
