The '''Tektronix 2792''' is a spectrum analyzer with a frequency range of 10 kHz to 21 GHz in coax, to 26.5 GHz with option 04. The minimum resolution bandwidth is 1 kHz, 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. | |||
The single and delta markers provide direct readout of frequency and amplitude information of any point along any displayed trace. Or, get the relative (delta) frequency and amplitude information between any two points along any displayed trace or between traces. | |||
Additional features include: Continuous Resolution Frequency Tuning, Up to 90 dB Viewable Dynamic Range, Built-in Frequency Counters Provide Frequency Determination to within 0.0000001%, Sensitivities to -134 dBm, Built-in Intelligence for Signal Processing/Marker Functions, Push Button Occupied-Bandwidth/Noise Normalization Functions, Macro Capability with Nonvolatile Memory, and Optional Switch-Selectable 50/75Ω Impedances. | |||

The Tektronix 2792 is a spectrum analyzer with a frequency range of 10 kHz to 21 GHz in coax, to 26.5 GHz with option 04. The minimum resolution bandwidth is 1 kHz, 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.
The single and delta markers provide direct readout of frequency and amplitude information of any point along any displayed trace. Or, get the relative (delta) frequency and amplitude information between any two points along any displayed trace or between traces.
Additional features include: Continuous Resolution Frequency Tuning, Up to 90 dB Viewable Dynamic Range, Built-in Frequency Counters Provide Frequency Determination to within 0.0000001%, Sensitivities to -134 dBm, Built-in Intelligence for Signal Processing/Marker Functions, Push Button Occupied-Bandwidth/Noise Normalization Functions, Macro Capability with Nonvolatile Memory, and Optional Switch-Selectable 50/75Ω Impedances.
Front panel inputs/outputs are: RF INPUT 50Ω N connector; 1ST LO OUTPUT SMA connector (Provides access to the output of the 1st local oscillator); 2ND LO OUTPUT SMA connector (Provides access to the output of the 2nd local oscillator); and CAL OUT BNC connector (Provides a 100 MHz ±10 Hz, -20 dBm ±0.3 dB signal).
Rear panel inputs/outputs are: PROBE POWER (Provides operating voltages for active probes); HORIZ|TRIG (EXT IN) BNC connector (A dual function connector: When in External Triggering mode the connector is an AC coupled input for trigger signals. When the TIME/DIV selection is EXT the connector is a DC coupled input for horizontal sweep voltages); MARKER|VIDEO (EXT IN) BNC connector (Interfaces to a Tektronix 1405 TV Adapter to display an externally-generated marker); HORIZ (OUTPUT) BNC connector (A dual function connector: Provides 110 MHz IF output as an input into the PEN LIFT connector.
