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, 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!

Typical applications include:

• TDR/TDT network and match analysis
• Spectral and flatness measurements
• Timing, jitter and crosstalk determinations

The PG900 Pulse Generators can partner the PicoScope 9300 20 GHz Sampling Oscilloscope in many of these applications.
