Hello All,
I am doing some random experiments where I want to generate a very fast rotating magnetic field using two out of phase sine waves (90 degrees separated). I wanted to ask you all here if you have ever seen any kits for a dual sine wave generator that allows the user to adjust the phase shift. I know that I could build something using Op-amps but I'm really looking for an off the shelf solution (a kit or something) that I can put together. If anyone is curious, the frequency range I'm aiming for is 1Hz to 1Mhz roughly. So far I found a nice DDS board on eBay that would do exactly what I want if it had two channels:

but so far I haven't found anything else. Any tips would be crealy appreciated.
Thanks,
