Almost all of the HP power supplies are equiped with a funny system to fasten the meters on the front panel : a plastic black bezel forms the outer cosmetic...
Many thanks for the helpful comments received. I spent a little time today investigating the low output problem on the 8640B. What I found is that a...
Thanks but what do you glue : bezel's and meter's case are plastic and super glue is not very performant ; the bezel and the meter without the spings on the...
Be careful with superglue on plastic. It can make a real mess, including crazing, etc. I'd use either RTV silicone rubber or a 2 part epoxy. FWIW, -John...
Sounds like you got lucky! I always like to see the response increase with frequency when fixing up a piece of broken gear, because it suggests that the pricy...
One reason that I sold my 8640B a couple of years ago was the prospect that the gears would eventually give me problems. I also got tired of cranking the ...
1. I've repaired a couple of split gears by epoxying washers onto them. A few gears are not amenable to this approach but with most it works great. 2. If you...
I think I have one of those filters out of an old 8640B carcass that had the times 2 option. All I need to do is find it. - Mike Mike B. Feher, N4FS 89 Arnold...
Hi John You're absolutely right. I'm dead lucky. Of all the things that could be a problem, this is about the least significant. There are none of these...
Hey Mike If you can find that filter it'll be just great. I daren't hope to hard, I've been so lucky already ;-) Bob, 5B4AGN ... had the ... time today ... ...
... Well, you almost certainly won't find the exact filter, but there will be something like it. I'd use generic search terms like "ghz filter" and "mhz ...
I'll find it, I'll guarantee that. I just will not promise when, HI. - Mike Mike B. Feher, N4FS 89 Arnold Blvd. Howell, NJ, 07731 732-886-5960 ... From:...
it depends on where they bust, really. as they deteriorate with age the stress from the springs can shatter the plastic frames almost anywhere. sometimes you...
I just got an 8484A power sensor to go with a 436A power meter I've had lying around. The 8484A is diode-based and covers .3nW to 10uW. I've never used a...
... Quite normal. In the '80's I wrote some ATE programmes using 8484A's and the normal measurement procedure was to turn the power off and zero before each...
G'day Dave I was missing a couple of the plastic doohickies on my plugins for my HP-140 and 141S and found that there were similar units on a wrecker Tek...
... I've repaired more than my fair share of them. The quickest way I found was to take a dremel tool with a small dental burr, and ream a channel in the gear...
Whoops !! sorry ! I made a mistake saying that Jose Gavila's website had the repair for the plastic gear, I didnt check my brain out of the vault this morning...
Hi all, I'm looking for a few things for the HP Laser Interferometer systems: First, for a 10714A Interface, I'd like a manual (Original HC preferred, but .pdf...
Hello Wade, No problem at my side!. In fact, I am about to add some info about cracked gears in my 8640B pages. I will let you know when I do. Regards, JOSE ...
There is a FTP site from Agilent for obsolete manuals. ftp.agilent.com default directory; /pub/manuals/ anonimous login. 3588A ; Getting started Guide and...
I have an 8640b and am curious as to how well the 11710B works in the combo and if it's convenient to use? Or is a seprerate HF gen better? tnx 73 Hank WD5JFR...
I've managed to bypass the filter by cutting the hardline off it and joining the two pieces together to give me an SMC to SMC interconnect. It's a bit...
Bob Glad to hear you have found the problem. I always have to wonder when sellers say the unit powers up but no further test made. Do you think the seller...
