The Tektronix 2797 is a spectrum analyzer with a frequency range of 100 Hz to 7.1 GHz and 10 Hz minimum resolution bandwidth, with digital storage.

Non-volatile memory (NVRAM) stores up to 9 separate waveforms with their readouts and markers, and up to 10 different front-panel control setups.

The single and delta markers provide direct readout of frequency and amplitude information of any point along any displayed trace, or indicate the relative (delta) frequency and amplitude information between any two points along any displayed trace, or between traces.

The instrument can selectively count one particular signal out of several that may be present at its input.

-The '''Tektronix 2797''' is a spectrum analyzer with a frequency range of 100 Hz to 7.1 GHz in coax.  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.
