content: Hello,I have this network analyzer that is unfortunately not used so often to offset the amount of space it takes. I can ship it to anywhere in the Europe for about 70 EUR. I know it's an old machine, but it works and it will be quite an effort to package it good enough to survive the trip. So make me a reasonable offer.. I know it's not worth many thousands of dollars as advertised on ebay.Last year I repaired it. One of the obsolete DA converter chips (on least accessible board) died. Also the springs on the buttons were replaced with strips cut from floppy drive. Works as far as I can test it. The cables and minicircuit parts see in pictures are not included in the price unless you really want them :-)

content: Sorry to be OT, but I'd be really interested to know what the 'mini circuits' are that you have attached, and what they achieve.I have a 4395A which didn't come with the impedance measurement jig, and although I've had some success with alternatives, I'm keen to open up other options wherever possible.Thanks!

content: the jig that usually attaches to the front of the analyzer is very simple. It's just one splitter and one directional coupler. I replicated the setup from the block diagram found in the original manual ("note") for the 41952A. Find it on keysight site, or try this link, page 16:http://literature.cdn.keysight.com/litweb/pdf/41952-90000.pdf?id=1901048I can look up the MiniCircuit part numbers if you want, but I just went for the cheapest that work up to 500Mhz.
