The '''Tektronix 492''' is a spectrum analyzer with a frequency range of 10 kHz to 21 GHz in coax, and up to 325 GHz with external waveguide mixers (492PGM N/A). The '''P''' suffix designation indicates GPIB '''P'''rogrammability | The '''Tektronix 492''' is a spectrum analyzer with a frequency range of 10 kHz to 21 GHz in coax, and up to 325 GHz with external waveguide mixers (492PGM N/A).

During the lifespan of the instrument the specifications and included options were altered several times. A major upgrade was the introduction of the '''492A''' in 1987 which added marker functionality and resolution bandwidths and the '''492BP''' in 1989 which added a counter and increased the displayed dynamic range. The '''492PGM''' is a cost reduced version introduced in 1990. Also see [[49X Series Comparison]]. | During the lifespan of the instrument, the specifications and included options were altered several times.
