HP / Agilent 81110A Pulse Pattern Generator, 165/330 MHz

The HP/Agilent 81110A is a dual-channel pulse pattern generator engineered for high-speed digital testing, characterization, and signal simulation. Operating at 165 MHz with 330 MHz capability through specific configurations, it delivers precise control over pulse parameters including width, delay, and amplitude. The instrument supports programmable pattern lengths up to 8192 bits per channel, accommodates multiple data formats including PRBS and user-defined patterns, and features both internal and external clocking options. Dual trigger input and output connections enable synchronized operation across complex test setups. With 50 ohm output impedance, fast edge transition times, and variable voltage levels spanning TTL and CMOS logic ranges, the 81110A addresses demanding applications in telecommunications, digital validation, and semiconductor characterization where signal integrity and timing precision are critical.
