Hi Group, I was wondering where I could get some probe tips for an HP8405A Vector Voltmeter? I would like to 3 if possible. Any ideas?

Dear all, I've continued to work on the 1725A and most recently replaced 32 capacitors (mostly tantalum, one electrolytic and one tubular ceramic that looked weird) on the three boards for main and

Hi Dickson, The Omron low signal relay that I used to replace the original Aromat relay in the div by 100 position has a manufacturer PN of G6AK-274P-ST-US-DC12 and at Mouser Electronics is priced at

Hi all, I've got an 8591C here that is missing some parts. Agilent does have stock, but their prices are way out of my budget. 0955-1005 UTG Impedance Matching Pad (75-50 ohm) It's also used on the

Hi all, I have a 182T with CRT horizontal scan failure, I haven't done any troubleshooting yet but according to the schematics I suspect 1853-0038 output transistors failure. I have search for a

Greetings, Thanks for the bandwidth! I'm looking for a fully functional and modestly priced HP-34703A DCV/DCA/Ohm meter "section". Of course, I'll gladly consider a complete unit comprised of either

Hi all, Really strange. I feel like HP made the 3324A later than 3325A. I saw the pictures of 3324A that having a dot matrix VFD display and new "HP logo", so 3324A seems to be a generator later than

Hi all, My 3325A has the attenuator board marked as "03325-66523 Rev B" which uses 4 yellow "PRINTACT" Latching Relay (12 BW4LD). I think Patrick's attenuator board is the newer "03325-66523 Rev C"

Hi all, My trusty HP-8640B (the first unit I got years ago) has suddenly stopped working :-(. I used it last time yesterday night and worked fine but today, upon powering it up, it shows an all-zeros

Leviton 1374-1 is the socket - had ne go bad in a power strip. Fits a .95" x .95" square hole. Add a -W if you want it in white. 5 bucks max at most industrial suppliers. Cheers, -B

Hallo Guy, we are talking about the IF section PowerSupply (85662A) yes? I concur with Jose, and can add that the +15V is the one you should concentrate on, because this is used as reference for -15V

Hello Guy, I know this is a very general message but I think it may help you... those HP multi-voltage supplies usually have one of them as a reference. If it is bad, all of them will show wrong

Hello group , I own an Hp8566B SA which went in trouble suddenly ,the display disappear and the instrument LED N°1 still lit, I have checked all the cables as state in the manual, and no results,I

Yep - might have to read up on the EMC - have a google for Henry Ott. Be careful you don't over invest in the SA. They are good but the YTO drift will still be there. If your tube is really suffed you
