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 something complementary to
the 8640B, the 8620, and the 10m-20G sweeper.

The candidates at present are the 3324 and 3325.

The questions are:

Of the 3324 and 3325, are there any of the A/B/C/etc variants to
favour or avoid?
Are there any other candidates to consider?

This is for home, not work. Cost is, of course, a consideration. I
already have 10mhz standard, so being able to lock to that is a plus.

Thanks,
Bob

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 or more years. Typically I check receivers and sweep
bandpass filters I am building, Xtals etc.
With .001 Hz res. it sure finds the exact peak.

Don't overlook the 3336.

The 3336 would meet the OPs requirements. Frequency coverage 10Hz to
21MHz with phase continuous sweep. AM and PM available.

The 3336 is sort of a companion to the 3586 selective level meter.
There are A/B/C versions with similar variations in input configuration.
The 3336 can be linked to the 3586 with an HPIB cable and track the
frequency (the manual says, I have not tried it yet).

The 3336 is not a function generator. Only sine wave output. It has an
input for 10MHz reference.

The 3314A is a function generator and in some ways more versatile than
the 3336. Sine, square and triangle outputs as well as burst (specify
number of cycles in each burst). And only half the size of the 3336.

It does not have the precision setting capability of the 3336 (and some
of the others mentioned).

I have never gotten the Easter egg to work with the one I have access
to. It looks like it is running, but no output.

User manuals for most of these are available on the Agilent web site.

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.

Someone mentioned the EPROMS on the 3314A. While I'm working on it,
should I read the EPROMS for future need?

Thanks for the input folks. Based on what you all have said, my needs and the availability from a list member, I'm going to go with a 3325.

I spent some time reading the manual this evening, which states that the 3325 will output up to 20,999,999.99 hz on the front connector and up to about 60Mhz on the aux rear connector. That might just be a very useful feature.

As a side note, the need here is for a sweeper that can be used in conjunction with a network analyzer at the lower frequencies. The function generation of things other than sine is just a bonus.

Thanks again for all the advice. Another question follows in a new post, so as not to hijack this one. ;)

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?

Take care in study the difference between the 3325A and 3325B. The extra
modulation source may be what you want. I have a 3325B and is happy

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.
I also put copies of eproms on Diddiers site for everyone.

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.
I also put copies of eproms on Diddiers site for everyone.

It is sometimes possible to read otherwise "lost" eproms by manipulating
their temperature downwards.
