Tektronix 2792 10 kHz to 26.5 GHz Spectrum Analyzers

The Tektronix 2792 is a spectrum analyzer engineered for precise signal characterization across a wide frequency span, from 10 kHz to 26.5 GHz. It delivers the measurement depth and dynamic range required for RF and microwave system validation, supporting telecommunications, electronic warfare, and EMC test applications. The instrument combines resolution bandwidth control from 1 Hz to 3 MHz, sweep times as fast as 200 µs, and noise floor performance down to -110 dBm, enabling detection of weak signals in complex spectral environments.

Advanced marker functionality - including single and delta markers - provides direct frequency and amplitude readout. A built-in frequency counter delivers accuracy to ±0.0000001%, critical for precision tuning and component validation. The reference level range of -117 dBm to +30 dBm and RF attenuator control (0 to 60 dB in 10 dB steps) support measurement of signals across a 134 dB maximum dynamic range.

Five triggering modes - free run, line, video, single, and external - accommodate both continuous monitoring and event-based capture. Configurable vertical display modes and frequency span accuracy of ±5% ensure repeatable, traceable results. The 2792 scales to 325 GHz using external mixers, extending capability into millimeter-wave applications without instrument replacement.
