Keysight N5181B RF Analog Signal Generator

Overview

The Keysight N5181B MXG X-Series is a high-performance RF analog signal generator designed to serve as a golden transmitter for R&D and manufacturing. It covers 9 kHz to 6 GHz with outstanding spectral purity, output power, switching speed, and modulation capability. The compact 2-rack-unit design reduces test stand footprint while delivering performance comparable to larger systems.

Key Features
