The HP/Agilent 81134A is a dual-channel pulse pattern generator delivering high-speed signal generation from 15 MHz to 3.35 GHz. Engineered for characterization of high-speed logic devices and digital systems, this instrument generates complex data patterns with exceptional timing precision and signal integrity. It supports multiple pulse generation modes—pulse, square clock, data, and PRBS sequences up to 2^31-1—with 12 Mbit pattern memory per channel and burst capability.
