I thought of that John, but the kit I have, a redpitaya + VNA, isn't fast enough for video. I'd imagine it would peter out at anything faster than 10 mhz. The VNA is nice, can draw smith charts in near real time at up to 60 mhz, so an AM radio station tower tuneup at 1 Mhz is pretty easy. That VNA s what I bought it for.
