PicoSource PG900 Series

USB Differential Pulse Generators

PicoSource PG900 Series Differential Pulse Generators – high-speed, low-cost, fast-transition instruments that can test transmission paths with a fast pulse, instantly simulating a wide-spectrum signal. These generators are ideal for high-speed broadband measurements such as time-domain reflectometry, semiconductor testing, gigabit port testing and radar systems.

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.
