content: Does anyone have page 5.2 of the HP 3325A manual? Adjustment instructions for the VCO frequency. I've searched the internet high and low and found maybe a dozen different PDF downloads, and every one of them goes page 5.1, 6.2, 5.3. Methinks Agilent/Keysight slipped up when scanning and every internet copy is of the same scan.If not I'll probably buy the Artek scan.

content: Hi,hp mixed the 3325A and B manuals in a puzzled way.. I searched a lot, but didn't find a good manual either. So I very quickly bought the ArtekMedia files, 3325B-IM -OM and -SM, which I would also recommend to you, also.Frank

content: Found this old scan that I think I posted here previously. You can also find hi-res scans of the 3325a schematics that I posted on ko4bb - the readily available ones published are pretty hard to read.

content: A bit off topic, but in case you or anyone else finds this useful, I just cleaned up one of these units this weekend and needed to replace the deteriorated foam filter on the fan. The key words I learned are "reticulated foam". 30 PPI (pores per inch) seems about right, and I was able to get a lifetime supply for $17 USD plus shipping from here:http://www.thefoamfactory.com/opencellfoam/filter.htmlI also ended up using this to cover all the vent openings in my home network cabinet to help keep it clean but still keep some airflow.

content: I have an original 3325A paper manual too. If Lorenzo_1 doesn't do it, PM me and I'll scan the 5.2 ... 6.1 pages.

content: Yeah I saw that. But it's only page 5.2, and you mentioned several more pages are missing. I meant I'd do them all, of which one is a fold-out. Bit busy atm though.

content: Quote from: TerraHertz on May 01, 2018, 03:47:21 amI think I wasn't as clear as I thought I was. I meant that the internet scans showed page 5.1 then page 6.2 and then page 5.3 i.e., that there is a ring-in where page 5.2 should be. I still thank you for the offer but I don't need the rest just yet.
