Keysight AP5042A Vector Signal Generator, 100 kHz–20 GHz (LN2)

Overview

The Keysight AP5042A is a high-performance G3 Vector Signal Generator designed for advanced RF and microwave testing. Housed in a 2U rack-mount chassis, it features a single-channel configuration covering 100 kHz to 20 GHz. The AP5042A LN2 variant delivers enhanced ultra-low close-in phase noise and long-term frequency stability across an extended frequency range, making it ideal for applications requiring the lowest possible phase noise floor. It is suitable for aerospace, defense, telecommunications, and product validation applications.
