The '''Tektronix 494''' 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. The '''P''' suffix designation indicates GPIB '''P'''rogrammability. The minimum resolution bandwidth is 30 Hz, and provides measurement resolution proportional to the frequency accuracy or span. | The '''Tektronix 494''' 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.
