The HP/Agilent 81105A and Agilent 81150A are pulse pattern generators engineered for precise signal generation across testing and design verification workflows. The 81105A delivers deterministic pulse control with configurable width, delay, and amplitude parameters, while the 81150A extends functionality by combining pulse generation, function arbitrary waveform, and noise generation into a single instrument. Both models support complex data patterns and PRBS generation, reducing test setup complexity and improving measurement repeatability across telecommunications, digital design, automotive, and radar applications.
