content: I REALLY want to purchase this 3324A signal gen (Agilent). This one is such a good price, but the error listed is not in the service manual, and well, I'm kinda scared to buy it.http://www.ebay.com/itm/HP-Hewlett-Packard-Agilent-3324A-21-MHz-Synthesized-Function-Sweep-Generator-/330964907466?pt=LH_DefaultDomain_0&hash=item4d0f0bb5ca#shpCntIdError is NO KEY-NO IR

content: And I REALLY purchased it just now!This teardown made me think the "No key - no IR" message might have been due to just a human input error:https://www.eevblog.com/forum/testgear/hpagilent-3324a-teardown/I'll see what comes out of this "purchase" aka "project".Cheers,Henry.

content: Seems a bit expensive to me, actually. The very similar 3325A can often be found for $100-$150, and as far as I can tell its only disadvantage is that it looks a bit crustier. Even has higher resolution. Am I missing a difference?

content: To be honest, I found the Ebay listing first and only when googling for the same error code as the OP I spotted this forum posting.Henry.

content: Ugh. You people. I have learned to never post the ebay link as well, but I just acquired a 33120A from craigslist for around $250.

Am I missing a difference?"I don't think I overpaid.While having similar specs, the 3325Ais actually a much older model (seems like a 1970's design), with the 3325Bapparently only a kind of facelift on the outside.The 3324A, on the other hand is a different system completely redesigned in 1988. Mine was actually made in late 1989 according to the IC date codes and has got serial number 2836G00418. Internally its about 80-90% SMD vs through-hole parts.Henry.

We have them in the labs at school and I like them a lot. I haven't had any luck finding things like that on Craigslist anywhere near me

content: Quote from: c4757p on December 09, 2013, 03:32:12 pmReally? From what I have seen, basic specs are really good, but the arb function is sort of a joke (I don't really need arb though). What else is good about it?
