You're right that if you want to have an automatic process then you'll need a mechanism that synchronizes the generator sweep with the measurement device. You could have your computer D/A generate the sweep and read it with its A/D. Then synchronization would be a matter of timing logic in your code. Alternately, if your signal generator has some sort of synchronization signal, perhaps you could read it programmatically. Either way, you'll need to have a mechanism in place.
