HP 83550A

    The HP 83550A is a high power 5.0-20.0 GHz plug-in that provides +20 dBm of output power to 18.6 GHz and +18 dBm of output power from 18.6 to 20.0 GHz.  This high output power is internally leveled with variations of less than 1.25 dB.  The output power has a range of at least 18 dB that is expandable to > 68 dB with option 002 (50 dB step attenuator) and the frequency output is accurate to 20 MHz. 

    The HP 83550A is also equipped to drive the HP millimeter-wave source modules directly.  These modules are frequency multipliers that effectively extend Hewlett-Packard's microwave sources like the HP 83550A to the millimeter-wave frequency range.

This HP 8350A  is in good physical condition.  Electrically it has some minor problems.  When adjusting the level control on the 83550A the output signal is periodically erratic.  When it settles, the signal is fine as can be seen in the photo below.  So bid accordingly.
