The Tektronix PPG3001 is a single-channel programmable pattern generator delivering data rates up to 30 Gb/s for high-speed digital testing applications. It generates pseudorandom binary sequences (PRBS) and user-defined data patterns with pattern depths to 4 Mbits per channel. The instrument provides DC-coupled differential outputs with programmable amplitude, offset, and crossing point control, making it suitable for characterizing modern communication interfaces and high-speed digital designs.
