The Tektronix PPG1604 is a 4-channel programmable pattern generator engineered for high-speed digital communications testing up to 16 Gb/s per channel. It generates PRBS and user-defined patterns with differential outputs on 2.92 mm connectors, making it ideal for receiver characterization, multi-channel validation, and crosstalk immunity assessment across 100 Gigabit Ethernet, 32G Fibre Channel, and PAM4 applications.
