Contact us for pricing and availability.

Designed for the Most Demanding Manufacturing and R&D Testing

Featuring high reliability and high power – all in two rack units (2RU) – Agilent MXG analog is optimized to provide the accurate and repeatable reference signals needed from the R&D bench to the production line. Add optional fast frequency and amplitude switching and MXG analog delivers the most value for your manufacturing investment by increasing throughput, maximizing uptime, and saving rack space. With scalable RF performance, the Agilent MXG analog is easily configured to meet your specific test needs, including LO and clock substitution, CW interferers, and modulated signals for analog communication systems such as AM, FM, and FM.

Maximize Uptime

Simplified self-maintenance decreases time for repair and performance verification, keeping downtime to less than 2 hours using field-replaceable assemblies.
