Quite a few typos scattered throughout, but still a very interesting historical document on HP/Agilent gear through the ages. http://cp.literature.agilent.com/litweb/pdf/5980-2090E.pdf (36 pages,

you can find the service man. for the B version at BAMA site Elie

In order to repair my instrument I looking to downloadable HP 8552A service manual any Help Apreciated Gabriele

Hello all, I have the following "vintage" manuals for sale: HP 522B counter $ 5.00 HP 5253B frequency converter (for 5245L counter) $ 10.00 HP 5440A digital DC

hi Dave, What are the magic buttons to invoke the self test on the 8050A please? Cheers Ian Du Rieu

That completes the continuum for me, then!!!! Very cool. I have a Fluke 8050A, a benchtop 4.5 digit DMM with battery option. It's now 20 years old. I have never calibrated it. I take it to work

Thanks to all for comemnts and suggestions :) Cheers Ian Du Rieu

I have a few HP3456As and have been pleased with them. The have a 1000 volt range and I think they can measure higher voltages than the HP 3478. The HP3456A's red LED display is easier for me to

The 3478A is certainly a nice meter, but I have a hard time getting my bench lighting right so LCDs are readable without too much light falling on the scopes. Too bad it doesn't have a backlit

A friend in town (W7TOM) just bought an HP 3478A, and we were both very favorably impressed by it. I have a HP 34401A on my bench which I bought brand-new for $1K, and the 3478A is almost as good at

Hi all, I'm looking at getting an HP meter along the lines of the 3455, 3456 or 3457. Its to be used in a small lab. I don't require any remote capabilities. I'm after a meter to carry on from

Hello Gary, read the thread about the HP 8405A Probe repair, the sampling head of the 3406 is quite the same as the 8405's are. And they usually die the same way. 73's Jorgen dj0ud

Thank you Jorgen. Your reply made me rethink my troubleshooting strategy. I had failed to consider that the diodes are at greater risk of failure, more so than the FET. The bad voltages measured

<dentist@n...> wrote: Hmm, surely, the fet could die, too, but "normaly" the probes fail with shooted diodes! And they could measure nearly OK but some parameters may have changed and so the bridge is

Hi Guys This is my first posting to this group. I am wondering if anybody knows about the "10032A" scope probe? Its a 100:1 probe has 3Mohm 3pF input loading and a max of 300V input. Its a really

I own the manual of servicing the 54111D model .There is only a block diagram for the 3 supplies: One is general and the 2 others are for "digital" and for "analogic" I will receive a second 54111D

Hi all, I hope you all enjoyed the Easter break. I am looking for a site to download a manual for the HP5245L frequency counter. Thank you Gary Beech VK2KYP

Looking to purchase a copy or original manual for the subject equipment. Arthur Shulman VE3ZV

I am saddled with a perfect 8405A with one defective probe. Swapping the sampling board between probe tips shows that the fault follows the board. The measured voltages are correct for the good board,
