HP 8558B Spectrum Analyzer with HP 182T Display
This is the versatile HP 8558B Spectrum Analyzer
with the HP 182T Display Mainframe. It has an operating frequency
range of 100 kHz to 1500 MHz. The unit works but appears to have
dirty or faulty switch contacts on the Span/BW selector and on the
Timing selector. The Manual sweep knob is missing as well. In the
photos below you can see the display with the spectrum analyzer tuned
to our local FM radio band. I also tested it with a 900 MHz cordless
phone and the signals showed up where they should. Check out the
detail specs and photos below.
Auction is for the 8558B Plug-in with the HP 182T Display Mainframe.
All of my auctions are sold As-Is.
