Looking for a cheap reliable solution to generate
a clean CW tone with acceptable phase noise
I am looking for a cost effective way to generate
a CW tone that doesn't cost an arm or a leg. Programmable
PLL via Serial? USB control? Any idea?
Just
don't want to end up using a signal generator for
2 fixed frequencies.

Are you looking for a single tone or 2 tone CW?
You could get a connectorized oscillator for a single
tone. Wenzel might be a good place to start..

Looking for two fixed frequency CW tones. Just need
to be able to switch between them in the same test
setup. Thanks.

Hi!
How clean is "clean"? What is "acceptable
phase noise"?
For that matter, what frequency
range are you looking at?
How far apart are
the two frequencies?
Companies like Analog
Devices often have evaluation boards for their RF
products, like PLL chips and DDS chips.
Good
luck!
