Jim, your mention of the HP 8640B made
me curious about the SSB phase noise
specs of the AD9166 system.? At 100 MHz
it appears to be equivalent to that of
the 8640B, but I couldn't find a spec
for the 8640B at 1000 MHz to compare
the two signal generators.? I agree that
the price of the AD9166 and frequency
coverage makes it an attractive alternative,
especially if low SSB phase noise is required
to serve as a reference source.

Hmm, one issue with the eval board is -- the dox for the eval board
show it being used with a Raspberry Pi 4 board, which is nearly as
much unobtainium as the USD$599 that the eval board costs, and right
now on the scalper's market, nearly as expensive too.

Still, it's a rather attractive bit of kit, and if I ever get my RasPi
4 from my globe-trotting brother, I might look at getting an eval
board.? For the price and the frequency span, it beats my old HP8640B
freq generator 10 ways from Sunday.

My birthday is next week, and Christmas is just around the corner.? So
maybe I know what I'm going to give myself.
