Some oddities [of 3325A and 3325B's]:
you can't get non-sine at as high a frequency on the front panel. I
think square waves go up to 10 MHz or so..
The backpanel waveform is always a sine, but not necessarily a very
high quality one.
The triangle and ramp signals only go up to 1

Please read the eproms. Mine are dead and they will absolutely die. The
mosteks are a known failure. If you can get me the images I will attempt to
integrate them into a modern 27128 or something and do that install. I have
had to do that on a couple of other types of HP gear.

The 3325 has an option for high voltage output from DC to 1MHz (up to 40
volts peak to peak at 40mA) with option 2 which can be handy sometimes.
Also, I remember the 3325B has an upgraded attenuator stack to improve
reliability as compared to the 3325A like I have.Can anybody chime in on
this?

The Easter egg plays fine on mine :-) It's rather lengthy, too.
Mine is in need of cal. I just replaced a dead lithium in it and when
I have time, I'm going to attempt the cal. I would love to be able to
sync it to my GPSDO if anyone knows how to add this feature.

The 3336 would meet the OPs requirements. Frequency coverage 10Hz to

I like the hp 3335. I also have the 8620.
Can lock to external 10 Mhz ref. Not sure 10 milli htz references are that
common. ;-)
Very accurate in frequency and output level and can do sweeps but to be
honest I have never used it that way. I have 3 of these and they have been
rock solid for 10 o
Thought I would consult the assembled wisdom here.
I'm looking for an HP frequency generator with sweep capability in the
1-20Mhz range. I can live with 1-11, and would really love 1-55, but
1-20 seems to be the most common. Other instruments I already own
cover 10 and up. The goal here is to have
19 matches
