Good afternoon list. I have an HP141T with the Hp 8553b and Hp 8552b plug ins. I am new to solid state test equipment and need some help. I have down loaded...
Dave, Interesting that you have that problem. I have an 8552B that exhibits the same symptoms! Or at least I think it does. My display (in log mode - linear...
Hi Dave. Thanks for ur comments. The way I tested the unit is I soldered a cable to the test points and removed the side panels on the main frame. Both the...
I am still looking for a 10mhz reference oscillator for this sig. gen. HP Part# 08656 - 16195 I believe. Does anyone know who sells the options for older HP...
Dave I have a cap. checker built into a vom. Would I be able to test the cap.s in the circuit without doing damage to surrounding componets? The checker is a...
Bruce: Check with George at the following website: http://www.advcommunicationsinc.com/ If you talk with him, tell him that Harold from Spartanburg recommended...
Hello Dave , In my many years of experience in service / fault finding it is my opinion that only two good ways exist for cap checking ... 1) knowing how the...

Hi Dave, well its going and working like its suppose to. I don't really know what I did except possibly clean the card edge contacts by taking the cards out...
Standard FAQ on the 141T equipment: put an extra washer under the D-connectors that join the RF and IF plugins, and/or bend the fingers out a little to improve...

I am trying to get my 8662A to work. I bought it knowing that it had problems. I now have most of it working but believe that one of the VHF (320-640 MHz)...
Dave, I know that you've already gotten the unit working. But, for future reference: One thing that I usually do first, when checking electrolytic capacitors,...
I've noticed so far three 436A power meters on ebay with light blue front faces, though everything else about the instrument seems to be in normal HP colors....
Hmm. Yeah, that's pretty ugly (I just looked). My 436A is the standard HP color. Interesting stuff; I didn't know they made anything like that. -- john...
I have made some progress since my initial post on my defunct 8662A. One of the 2N5397 JFETs in one of the oscillators was defective and now both oscillators...
I think the best old paper capacitor is a replaced one (with a modern plastic type) however if you want to test them a Megger (high voltage insulation tester)...
Hi, Does anyone have the part number for the woven cable that goes between a HP 1650B series logic analyser and the pods? Even better - does anyone have any...
Mike, you might write to Tom Bruhns (k7itm (at) aol.com, or tom_bruhns (at) agilent.com) and see if he can hook you up with the in-house service procedure....
Thanks for the tip John. Another list member was able to provide me with the schematic (from a book by Ulrich Rhode), but of course no information on ...
That reminds me of a really cool tip that most people haven't noticed yet. Amazon provides full-text searches of many of their books now, including technical...
Seems to have been a momentary glitch in the Matrix; it's back up now. -- john KE5FX ... From: John Miles [mailto:jmiles@...] Sent: Friday, August 06, 2004...
That's pretty neat. Even if you do have to give them a credit card number. Thanks for the tip. I did email Tom and hope to hear back as he is probably my best...
The bad news is the last time I poked around, the assemblies themselves are proprietary to Agilent/HP. They are made from what appeared to be a standard Gore...
I just picked up an HP-8654B signal generator with the HP-8655A synchronizer but I am having a problem with the combination. When I try to lock the sig gen...
