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 minimum resolution bandwidth is 100 Hz, and provides measurement resolution proportional to the frequency accuracy or spanWith non-volatile memory (NVRAM) you can save up to 9 waveform displays, up to 10 complete front panel measurement parameter setups, and 8 K for programming macros of commonly used routines.

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]].
