PicoSource® PG900 Series 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. These signals, combined with differential capability, are valuable for making high-speed broadband measurements in many fields such as time domain reflectometry, semiconductor testing, gigabit interconnect and port testing, and in radar systems. High-speed differential data is becoming the dominant measurement challenge in digital, computing, interconnect and telecommunications systems. Despite this need, cost-effective, fast-transition differential pulse generators were hard to find ... until now.
