HP Agilent E4407B spectrum analyzer up to 26.5 GHz with option H57.
The optical and mechanical condition is really not good, there are scratches on the display, the cover of the floppy is missing, the carrying handle is off on one side, cracks in the protective rubber...
However, electrically it seems to be working, according to the label it was last calibrated on December 14th, 2022, the backup battery was changed on September 14th, 2022, self-test shows no errors, Ref Out shows a correct measurement, all buttons and dial work.Due to the external condition and a complete functional test that was not carried out, there is no functional guarantee for the device. Since the calibration wasn't that long ago, the self-test has no errors and at least the reference output was measured correctly, I suspect that it works.
The user-defined option H57 is installed, which includes the options: 1D5, 1DR, A4H, AYX, BAA, AYZ.1D5 Highly stable time base1DR narrow RBWA4H adds GPIB and parallel portAYX Fast Time Domain Sweep; Includes IF, sweep and video output connectionsBAA FM demodulation/deviationAYZ External Mixing
