PicoSource PG914 - USB differential pulse generators
The fast-transition pulse can stimulate a transmission path, device or network with a broad spectrum signal in a single instant. Such a pulse is very useful for many of the high-speed broadband measurements that we need to make; for instance in time-domain reflectometry/TDR, semiconductor test, gigabit interconnect and port test and in radar. Differential high-speed data in particular dominates the measurement challenge in our digital, computing, interconnect and telecommunications systems. Surprisingly, cost-effective fast-transition differential pulse generators have been very hard to find... until now!
