I am way better at analog than digitalSo one of these can generate a quadrature signal, e.g. CH1=sine, CH2=cosine?
I've looked into using high-speed power OP-amps (not IC's). They're pricey, though. Will such beasts work? My analog skills suck.
an arbitrary wave form generator will make whatever you want.
the ones I have can be linked together, so I can make 4 phase power if I want (why I bought them)
I am only using one of them for this test setup
it has some internal sync that you can then set a phase angle from,
so you can set sine wave on the first channel and then set 90 degree (or any number you like) delay for the second channel
it has very good defaults for waveshape types, and there are lots of them.
if you plug it into a computer, you can literately draw any wave you want and upload it.
it has 100mA out and adjustable DC bias, so you could drive a mosfet directly off it if you wanted to (I would not do this without additional protection circuits as mosfets tend to fry in experiments, and they conduct back main power into what use to be the gate, frying whatever is connected )
some fancy OP-amps have built in protections so they don't break easy, got a part number for what you are thinking about ?
