We use an Agilent 8644B where I work as the master oscillator for an
electron cyclotron storage ring. Electrons at 2GeV don't like to be pushed
around and are very sensitive to phase noise, so the feedback loop that
adjusts the frequency uses the FM input for fine adjustment.

Hi
Having hooked up a 9854 and tried it with realistic settings - it's not that
great. If you run it at "magic" frequencies (where it's essentially just a
divider) it looks like a divider.

Hi Anders:
The HP 8648() series signal generators were made for applications that required
very clean signals, like testing pagers.

I want to use the synthesizer as a flexible offset source for beat
frequency measurements. So the frequency range is 5 to 30MHz approx.

They use a pretty interesting "rational approximation frequency synthesis"
which they discuss in detail in their operating manual. This allows them to

Hi
What frequency range?
Conventional DDS isn't likely to do the job.

I have been looking around for a very stable synthesizer(http://www.febo.com/pages/pts_synth/).
Is there any other really good alternatives to the PTS synthesizers? DDS?
HP?
