    Product description

    The Tektronix PPG4001 PatternPro® programmable pattern generator provides an unparalleled combination of industry leading performance, features, and ease of use. Design validation of today’s demanding high-speed applications requires instruments that produce the highest quality signals and enable programmable controls while being simple and easy to use.

    Fast rise time and low jitter are critical performance parameters and the PPG4001 delivers typical 200 fs inherent RJ with 8 ps rise time. Within seconds of powering up the instrument, a first time user can be creating high-performance programmable patterns to test a DUT. In addition, the PPG4001 offers comprehensive jitter insertion for stressed receiver testing and similar applications.

    The PPG4001 may be paired with the PED4001 40 Gb/s programmable error detector to provide a complete BERT system that includes control and analysis software.
