Man, your 8566B is in beautifully clean condition. Mine got put in a box with essentially no padding to the outside and between the two units and shipped to me. It arrived with all the corners smashed, the the units scratched up, and the screen destroyed and the keyboard cracked and many of the buttons pushed in and not working properly anymore. The guy I bought it from on eBay was a complete asshole and claimed he'd done everything right and the problem was UPS. After being screwed around by this guy for a couple weeks eBay did refund my money. The guy refused to take the 8566B back. Over time I was able to buy all the parts to repair it, screen, keyboard, etc. It's a wonderful piece of equipment - just mine is not in great cosmetic external appearance.
Yeah, these things are so heavy and typical cardboxes simply won't hold them. When mine arrived the boxes were almost destroyed and there were wholes on the outside of the boxes. Luckily the unit was shipped in two separate boxes and there was some bubble wrap so the only thing that was wrong was a dented corner which I was able to pull out...
Nice video Kerry. I believe you should have a say 3dB attenuator at the mixer IF output. The mixer requires nice 50 ohm termination on all its ports to meet its spec, but in your setup the termination on IF port depends on what DUT you are measuring.
There's just something about a piece of test gear that starts up and sounds like a jet engine that is appealing (well, at least for a while!). And thank goodness for the normalize button on my SA! Your trick reminds me of getting a scope to make a differential measurement. Thanks for sharing Kerry, always interesting stuff you bring to us! ;-)
Thanks Dino! I guess I will need to move that HP8566B off the shelf to troubleshoot the YTO unlock error soon before I can use it any further... I have been dreading that as the whole thing weights close to 150 pounds!
Hi Dino, yes, the noise gets old after a while. But a 10GB enterprise fiber switch or enterprise server put the 8566B to shame if we're talking about sounding like a jet engine at startup and a sound that is wholly intolerable while running :-)
@Kerry, please post a video of your YTO unlock investigation. I have not experienced this but having a video as reference to diagnose this issue on RUclips would be great.
Mr Wong Great video and I may follow your lead with my 8566B. Have you looked at the cheap Chinese VNA's on ePay and Amazonk??? They start around $50 and go to almost 1 GHz. I hope you will do a video on this unit at some point. I watched Joe Smith's "RF Engineer," excellent review on youtube. It looks like a lot of bang for the back. I ordered one recently to hold me over until I find a good on a decent used HP unit... Regards, Glenn, SC

Yes. That would definitely ensure proper impedance matching but at the same time sacrifice a bit of dynamic range.

I will definitely start investigating soon. Stay tuned!
