The '''Tektronix 2782''' is a spectrum analyzer with a frequency range of 100 Hz to 33 GHz in coax, to 325 GHz with external waveguide mixers.


The '''Tektronix 2782''' is a spectrum analyzer with a frequency range of 100 Hz to 33 GHz in coax, to 325 GHz with external waveguide mixers.
It has digital storage including non-volatile memory for storing up to 20 separate waveforms with readouts and markers, and up to 20 front-panel control setups.
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.
