Hewlett-Packard Spectrum Analyzer with 8555A RF section, 8552B IF Section, and 141T display

The 8555A is the microwave RF Section for use with 8552-series IF section and the 140-series display section.  Together they comprise a receiver that electronically scans an input signal and provides a visual display in the frequency domain.  Input signal amplitude is plotted on the CRT as a function of frequency  The amplitude of the CRT is calibrated in absolute units of power (dBm) or voltage (µV/mV) (50 ohm system):  accordingly, absolute and relative measurements of both amplitude and frequency can be made.

The analyzer RF and IF sections form a highly sensitive super-heterodyne receiver with spectrum-scanning capabilities over the frequency range of 10 MHz to 40 GHz in 14 frequency bands.  The analyzer presents a calibrated CRT display up to 2 GHz wide.  Absolute calibration accuracy is maintained from 10 MHz to 18.0 GHz in 10 bands, using internal mixing.  The frequency range from 12.4 GHz to 40 GHz is covered in 4 bands through external mixers.

The manual entitled Understanding and Operating the 855A Spectrum Analyzer and 8445B Preselector is a good tutorial for this unit.
