The Tektronix PPG3004 is a 4-channel programmable pattern generator supporting data rates up to 30 Gb/s for high-speed digital testing and characterization. Each channel delivers independently programmable differential outputs with flexible pattern control, making it ideal for 100 Gigabit Ethernet, DP-QPSK, and receiver validation. Part of the PatternPro® series, the PPG3004 combines cost-effective operation with the precision needed for demanding signal integrity applications.
