The '''Tektronix 2755AP''' 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 100 Hz, and provides measurement resolution proportional to the frequency accuracy or span.  In addition to conventional digital storage features, non-volatile memory (NVRAM) stores up to 9 separate waveforms with their readouts and markers, for later recall for additional analysis and comparison, and 10 control settings.  Also, store up to 39 preselector peaks and 12 external band peaks.  The instrument can selectively count one particular signal out of several that may be present at its input.
