The Tektronix 2782 is a spectrum analyzer with a frequency range of 100 Hz to 33 GHz in coax, to 325 GHz with external waveguide mixers.
It has digital storage including non-volatile memory for storing up to 20 separate waveforms with readouts and markers, and up to 20 front-panel control setups. The instrument can selectively count one particular signal out of several that may be present at its input.
Single and delta markers provide direct readout of frequency and amplitude information
