The Keysight (formerly Agilent) 81150A is a versatile, high-precision Pulse Function Arbitrary Noise Generator. It is designed to deliver fast, accurate signals for performance verification, characterization, and worst-case scenario testing. It offers up to 120 MHz pulse generation with variable transition times, 240 MHz sine waveforms, and high-fidelity 14-bit, 2 GSa/s arbitrary waveforms with 512 kSa memory per channel. Configurable with 1 or 2 channels, it provides differential outputs, extensive modulation capabilities up to 10 MHz, and specialized noise generation featuring a selectable crest factor and a repeatable cycle of up to 26 days.
