The '''Tektronix 2794''' is a spectrum analyzer with a frequency range of 10 kHz to 21 GHz in coax, to 325 GHz with external waveguide mixers.  The minimum resolution bandwidth is 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 9 separate waveforms with their readouts and markers, for later recall for additional analysis and comparison.  Also, store up to 10 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.
