AD9851 Tracking Generator board/schematics?

Postby WA4OSH » Fri Dec 14, 2018 1:42 pm

I'm a little late to the AD9851 tracking generator project. Did someone document which board works best and how to connect it to the PC that's running the SDRPlay?

There we go,
I made 2 pcs ad9951 DDS osc. master oscillator with a saw resonator at 433 MHz.
I was looking for little osc. noise.
At 40 MHz the harmonics and spurs are coming up.
Regards,
(With a 1 GHz resonator all things between 0 and 100 MHz must be clean (enough :) )

Hi.

I too am late coming into the discussion for the tracking generator, like the first author. Again, is there some information on how to connect the AD9951 board or similar, with an Arduino board and subsequent control by a PC?

I gather that the AD9951 is quite suited to doing frequency sweeps, unlike other DDS devices.

I have searched with Google with little joy. There is a mention of it in the spectrum analyser documentation, but little specific.

Hi Drew

I've just covered this in another thread. Have a look at this: viewtopic.php?f=12&t=4341

This should cover what you need to know. Any problems or queries, please let me know.

Steve
