Sorry, I can't order your board - although I'd like to. My Significant Other went on ebay and bought me... the AD9851 board. Sure it has slightly better specs, but the dimensions [and pinout] make it

If you want higher frequencies, you need a different generator - or redesign the current one. The AD9851 typically runs at 180MHz, and the "cleanest" sine waves are under 60MHz. Due to the wonders of

That's fine - if you only ever go above 35MHz. I'd say it complements the AD9850 / 9851, rather than replaces it: put them together for increased spectrum coverage. Personally, for a Network Analyser,

Sorry if I'm asking questions that has been answered elsewhere, but - what are the PCB dimensions ? I think the AD9851 board I have is "Type I", and I'd rather be sure before buying the board and sear

Thanks for that - as I suspected, printing the PDF on A4 paper [scaled to fit] is enough to distort the dimensions. I'll send you a board request shortly. --Alan

If I was starting all over again, I'd get the DDS-60 module. Yes, it costs more - but it has a buffer amp and low pass filter, ready to go. Just my $0.02. --Alan Campbell

For higher frequencies, I'd suggest a PLL setup. A VCO running at the right range, also feeding a frequency divider [help square up a sine wave] and phase detector. Reference signal from Si570, low pa
