Would anyone have any interest in my Service Training manual for the HP 8566A/B and 8568A/B?
This is NOT the service guide but rather a thick binder covering the circuit description with some schematics. This book was used during my service training at a two-week seminar at HP's Rohnert Park facility for these models.?

As I wrote above, that has its uses but it has its problems for the reasons I stated.
Another trick I forgot to mention is one that express-test (Alltest, in the USA) do. If you look they sell small quantities of HP feet. You buy 1 on one auction,? 2 on another auction.? There is no auction where you can select the number you want.?
When I was buying an item from them,? and wanted 30 feet, they insisted that they were purchased on eBay.? They told me that they get them made, sell them at cost, with the purpose of boosting feedback.? So I had to purchase about half a dozen auctions to get the feet. So they got 7 positive feedbacks from me.
> If someone's been on there for years and has a 100% feedback rating, they're probably very safe to buy from.?
As I note, yixunhk, from China,? is one dodgy seller who keeps their 100% rating by some dodgy means.
Another thing,? if a buyer leaves no feedback,? I am pretty sure I read it counts as positive at some point.
> Another thing I've found that's great to buy on Ebay: batteries.? I needed some CR2012 batteries, which you can easily pay $3 each for in a retail store.? There's sellers selling these things for 10/$5 or something like that; they ship them to you in a letter-size envelope, taped to a piece of paper! Obviously they buy them in huge quantities and sell them sans packaging at a profit; at Walmart you're paying for fancy packaging and retail overhead.
Now batteries is one item I will *not* buy from eBay. The probability of your $0.50 battery being a poor counterfeit part, with the risk of leakage is very high.

Re: HP DVM / DMM technological history
is a very long list of test equipment model numbers with brief description. The person who created the list also has links to photos of a lot of the equipment. I stumbled across it, while searching for a manual for an obscure piece of test equipment.

Re: Recommendations for a synthesized 20GHz+ RF gen
Bob Dildine is correct and if you feel the same way, then the 8341 may be your best choice. (It's almost the same as the 8340.) It has two downsides. It's extremely heavy - probably the heaviest piece of test equipment from that era. And it is really loud.
But, it goes from 10 MHz to 20GHz and it doesn't require software for adjustments. BTW, the 8341 can be made to go to 26.5 GHz, you will have to align it in that last band and push some keys on the front panel to enable that feature.
BTW, I think I once aligned the 8566 front end using a 321.4 MHz source, the first LO and a mixer. Obviously, it wasn't a great job, but if you have no other equipment, you can get things going that way.

Re: Recommendations for a synthesized 20GHz+ RF gen
Siggi,
I have both an HP 8672A (2-18 GHz) and an HP 83732A (10 MHz - 20 GHz). I'm partial to the HP 8672A because that was my first project of my 30 year career at HP but I really like the HP 83732A. However, the 83732 requires specialized service software that runs on the HP series 200 or 300 computers to make any adjustments. This software writes calibration constants into ROM. I'm stuck with uncalibrated power output (it's off by 4-6 dB and not monotonic) and no way to correct it. The 8672 was done before the era of computers and all of its adjustments are done manually as outlined in the manual.
So whatever you choose, be aware that a fixer upper might require service software that is now unobtainable and runs on computers that are old and obsolete.

Re: eBay buyer protections are poor
I have had excellent experiences with Ebay, I just received a nice clean working HP85046A from the US, a Morse taper reamer from Ukraine, and two lots of PCBs from China (plated thru holes, silk screened, 10 for $25 plus a reasonable shipping charge. However they sent 11 so should I demand my money back?). All these items arrived in less than 10 days. Yes Ebay and Paypal are getting a bit greedy but I remember trying to sell stuff with newspaper ads that cost $30 back in the ¡®70s. You do have to be a bit careful and I always look at the negative ratings to see what the complaints are about. Some people just bitch ¨C the $2 diamond studded watch was Gold, not Platinum as described. Most vendors will try very hard to make you a happy customer. Complain to them first, don¡¯t raise a case until you have to. PeterB ?

You do have to have good hamfests. It also depends on what you want to buy and whether or not the market it there for such things. For a "relatively zero" probability event, I've managed to do fairly well, although one could always do worse, or better.

And required games and who to trust and who is trying to cheat you also applies on ebay. The feedback rating has become, apparently lately, less than reliable. You can at least examine the purchase carefully, may be able to plug it in, and can decide to buy or not. If it looks like junk or is in need of repair, you offer accordingly. You can always walk away.

You're going to hamfests that are too far away, for one. There are always things on ebay that you will not see at hamfests, and you will also find things at hamfests that are wildly over-priced on ebay.
Ideally, you'd make use of both.

Re: eBay buyer protections are poor
I've been using Ebay since 1996 (when it was called "AuctionWeb") and have a 100% rating.? I don't use it that much any more, but it's invaluable for some small and/or hard-to-find things, especially on the used market.? You can get much better deals there than on Amazon, depending on what it is (esp. if it's used or closeout).
Here's a few pieces of advice: - look at where your seller is located.? If they're in China, only buy from them if you're willing to eat the cost if it either never shows up or is a piece of junk.? I wouldn't buy anything shipped from China unless it's under $10.? Buyer protection may save you, but is it really worth the bother?? Just buy from a US seller and avoid all the hassle. -? Look at the seller's feedback rating.? Look more carefully if you're buying something valuable, look at the negatives and see what they say.? If someone's been on there for years and has a 100% feedback rating, they're probably very safe to buy from.? Otherwise, take into account how much volume they do (I have a perfect feedback rating as I said, but my volume is very low because I've never sold that much stuff on there, just some secondhand things mainly).? It's probably impossible to sell 10,000 items without getting a few disgruntled customers here and there.? Some people are just weird. - Comparison shop on Amazon and other places.? Ebay has high fees (esp. for low-volume sellers), so you might get a better deal elsewhere.? Try Craigslist if it's something that makes more sense to sell locally.? Personally if I'm buying something new, I go to Amazon first, as they usually have the best prices, free shipping, and an easy return policy and system.? If it's expensive, I'll check around, but if it's something Amazon is selling directly, the price is usually very good, but if it's an affiliate, not necessarily.? Ebay is my go-to place for weird small stuff.? So when I wanted to buy some 6x6" aluminum plates, for instance, instead of getting reamed at McMaster-Carr, I went to Ebay and got them dirt cheap from some small (US) seller.? When I wanted a used cellphone, and an Otterbox for it, I went to Ebay (the Otterbox was new, but since it was for a 2-year-old model, it was $12).? If I want to buy a used off-lease office laser printer, Ebay is where I go for that.? Ebay is simply the best place for secondhand and closed stuff like that; there's tons of high-volume liquidation sellers who use it for that.? Another thing I've found that's great to buy on Ebay: batteries.? I needed some CR2012 batteries, which you can easily pay $3 each for in a retail store.? There's sellers selling these things for 10/$5 or something like that; they ship them to you in a letter-size envelope, taped to a piece of paper! Obviously they buy them in huge quantities and sell them sans packaging at a profit; at Walmart you're paying for fancy packaging and retail overhead. - Research your product and know what you're buying.? Sellers don't always know exactly what they're selling.? It's better to ask a question, or skip the sale, than get into an argument over the specs of an item. - Don't get emotional about Ebay's customer service.? Sometimes it works, sometimes it doesn't.? It's a big corporation, and they're not going to do everything right.? Refusing to use them out of spite will cut you off from a lot of good deals. Remember, caveat emptor.? If you want a no-questions-asked return policy, go to Walmart.? Ebay is not a replacement for Walmart, nor vice versa.? My phone's Otterbox is on sale at Walmart for $45, full price, and not discounted, but Ebay had it for $12.? From a high-volume seller with a good record, that's worth the risk to me.

Re: Test Equipment where battery failure causes SERIOUS problems
This may not be the best place to mention this but I have an Advantest R3131 spectrum analyzer that had its battery fail and as a result "forgot" that it has a tracking generator installed.?
I have reviewed the documentation manuals, I have searched high and low on the internet for information on how to restore the tracking generator installed option bits but have had no success.?
I have asked on the Yahoo Advantest instrument forum.?I have checked with several instrument repair groups and they are all clueless. I even checked with Microlease, the official designated repair group for Advantest in the US. They want to charge me $4k for fixing the issue, which is completely ridiculous and way outside my retiree amateur radio budget.?
Does anyone here in the HP instrument forum have any experience fixing this issue with the Advantest R3131 analyzer or perhaps knows someone familiar with this analyzer? Perhaps a former instrument repair tech that might have knowledge that will help me solve this issue??
I would appreciate any help you can give me. I'm desperate. That's why I'm lurking here in this HP forum. :)
Thanks, Leland K9SDR
