Keysight N5181A MXG RF Analog Signal Generator Description

The Keysight N5181A analog and vector MXG signal generator deliver unmatched performance in five key categories: phase noise and spectral purity, bandwidth, EVM, ACPR, and output power.

Advanced real-time applications

Perform advanced receiver testing compatible with the latest standards using the MXG Signal Studio software: define signal parameters, transfer them to the instrument, and use closed-loop or interactive control during signal generation.

Lower cost-of-ownership

X-Series signal generators are designed for high reliability and simplified service. One key example is the self-maintenance strategy: if onsite repairs are ever needed, they can be completed in less than two hours with our refurbished-parts exchange program.

Keysight N5181A Features

  • Generate accurate and repeatable reference signals for R&D to the production line with high reliability and power
  • Increase throughput with fast switching options
  • Configure to meet your specific test needs with scalable performance
