I got a call from a really nice guy who has a tiny company in the Bahamas. Our gear is too expensive for his application, but it could be done with a PCIe PC-plugin board that has an FPGA and a fast DAC. It would need analog bandwidth in the 30 MHz range, maybe 100M samples/sec or so. He would need help to program the FPGA, since the signal set that he needs to generate is kind of weird, but not actually super complex.
So, does anybody know of an existing board that would work? I'd expect that lots of people make stuff like this and are used to helping customers customize them. We're talking tens of systems here, not enough for a custom board design.
I'll do a little googling myself, but I thought I'd ask.
