HP 8722D
« on: August 26, 2020, 04:45:43 pm »
A local surplus place I sometimes buy from has this for sale (ending soon!) and I'm a bit surprised at the bids.  Other than a deep-pockets company or government lab that would just buy new anyway, who would be in the market for this monster and what would they do with it?

A 3.5 digit 4.5 digit 5 digit 5.5 digit 6.5 digit DMM is good enough for most people.

Look at the prices of new VNAs with similar specs, then the $14k is kinda cheap, if you really need a VNA.
What to do with it? Measure S-parameters of the components you're interested in, between 50MHz-40GHz.

40GHz is a bit much for my hobby stuff, but a VNA from like 0-3GHz to measure things like amplifier gain/phase is a nice toy to have, much more accurate/easy to use than with oscilloscope, so I kinda understand why people pay that much, especially if it goes up to 40GHz.
