I just bought an HP 3325A synthesizer/function generator that I really like (for some things anyway) in about that price range. What you get is probably dependent on what YOU need though. This thing is pretty limited but this particular one has the high voltage option so the output goes up to 40 volts up to 1MHz. It only goes to 20.99999999 Mhz (at up to 10V I think) but for 99% of what I do that's just fine. It has a 10MHz external reference which I hook to either an Rb osc or a Thunderbolt depending on what I'm doing. It's pretty neat to see all the digits match between the 3325A and the 5335A counter. Of course, that's being clocked by the same oscillator too.
Also, I noticed on some signal generators, dropping the output down to a few mV distorts the signal. What I learned to do was send my signal out at about 1 volt ((RMS or p2p, doesn't matter) and go through a step attenuator to drop it back down so it comes out clean. -Bob, N3XKB On Fri, Jun 19, 2009 at 6:04 AM, Patrick <optoma...@rogers.com> wrote: > Hey everyone > > Sorry for the off topic post.
