The '''Tektronix 494A''' 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 10 Hz, and provides measurement resolution proportional to the frequency accuracy or span. With 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. | The '''Tektronix 494A''' 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.
