Re: LF: Ramped BPSK

Try the Anlaog Devices web site - www.analog.com   

I built my own PCB,   http://www.g4jnt.com/AD9852module.pdf   (PCBs are no longer available for that, though).  That particular DDS is a bit out of date now.  I use it  for this job as I have a few modules left, and it is one of the few devices  with both a 48 bit frequency setting register and amplitude programmability.

attenuated.

But, does that bring back the audible clicks from the PA
and coil?

I'm keen to have a play with these DDS chips.  Is there a
recommended evaluation board?
