Some Pictures of My HP 8566B Spectrum Analyzer

The latest addition to my lab is an HP 8566B spectrum analyzer. This isn’t just any spectrum analyzer, it was perhaps the best spectrum analyzer money could buy back in the late 80’s. While it was discontinued in 1997 and has long become obsolete, its performance remains quite impressive even by today’s standards and still rivals that of many of its modern counterparts.

Ever since I got my HP 436A power meter, I have been looking around hoping that I could obtain a compatible power sensor (e.g. 8484A) at a reasonable price to go with it. But these power sensors are quite expensive on the second-hand markets and even a non-functional unit can cost more than a hundred dollars. Since like most hobbyists, my requirements for a power sensor is not that high, I decided to build a simple RF power detector myself.

Those cheap sub-$10 multimeters are usually too inaccurate to be trust-worthy for any kind of serious measurements. That said, because of their affordability they remain quite popular. I usually would bring one of these when doing casual work in the field so I do not have to worry about losing it or damaging it.
