Re: HP3325 - no output, but sync works
Joe and Szabolcs: thanks for the ideas! I have not yet opened the box (after years...). Since this unit came from my employer, who has a metrology, and calibration group, I¡®m betting on the bad

Finding feet for older HP gear
Hi all, I have a number of examples of the older style case HP gear (8640B, 8405A, and now a 3440A) that all lost their feet at some point before I got them. I know these feet are rather scarce, but I

Re: [WANTED] HP 85700A 32kB RAM card
The logical step in any situation is to replace a failed component.? But when one relies 100% upon a mission critical part, without knowing that it failed, they can be subtly surprised if it had

Re: Fuses for 5350B input 2 [lower frequency input]
Thankyou Askild, and Greg. I have an inquiry in to one of the suppliers on eBay. Shipping showed as about $350 - I think this is a little too high, and might be an error ;). I have a 5350B on its way

Re: A dirty way to get more frequency resolution out of a signal generator
I should point out I have not attempted this as I had no reason to, why I am sharing this is that it appears to be an unusual exploit should you desire a more fine frequency control though not without

A dirty way to get more frequency resolution out of a signal generator
To put simply, take a function generator such as a HP 3325B, set the output to 0dBm at 10 Mhz, plug that into the reference input of the signal generator. Then if you want a frequency of 100 Mhz just

Re: HP3325 - no output, but sync works
Hi, If you do not hear the relays clicking, first thing to check is the ribbon cable between the attenuator board and the A14 board. They are notoriously bad, to the level that on one of my 3325A I

Re: Fuses for 5350B input 2 [lower frequency input]
Don, If I¡¯m not mistaken, HP part number 2110-0301 crosses to a Littelfuse part number 0275.125 under their Picofuse product brand. This fuse was obsoleted in 2007 along with many others in this

Re: HP3336b
What type of connector are you referring to? Apart from the fact that "RF phono" seems an oxymoron to me, I am not aware of HP widely using low-cost connectors. Are you talking about RCA/cinch

The additional effort to attach an external power supply to keep the memory contents is really not needed. In the referenced Assembly Repair manual there's a section on how to replace the A16A1BT1

I just tested the ZSETADDR and ZRDWR? commands given there, on my HP8595E. They seem to do something, but not what I'd have expected. Subsidiary problem: My 8595E display centering is a little off,

That does sound like a drifted master oscillator, or perhaps further down the chain, but so far I can't find a table of error messages for the 3336. However, on a more general note when working on
