Would digital inputs be good enough? Suppose you feed several 10 MHz signals into a FPGA and program it so each input signal drives a counter. Ignoring implementation details like synchronization, is that good enough to be interesting? I'm assuming you have a PC that grabs all the counters every N ticks/seconds/hours/whatever. Note that there is another clock involved. It's the one driving the FPGA or PC. How much would it help if there was an A/D on each input channel and the FPGA could capture a dozen samples on each signal around the time that it latches a copy the counters? -- These are my opinions, not necessarily my employer's.
