The HP/Agilent 8165A is a 50 MHz programmable pulse and function generator delivering precise, multi-waveform signal generation across 1.000 mHz to 50.00 MHz. Built for laboratory and field testing, it generates sine, square, and triangle waveforms to 50.00 MHz, plus pulse and ramp outputs to 19.99 MHz with selectable duty cycles and symmetry. Frequency resolution reaches 1 µHz in the millihertz band, with ±0.001% accuracy and ±1 × 10⁻⁴ synthesizer stability—enabling tight tolerance measurements in component characterization, circuit validation, and system integration workflows.
