The Keysight 70612B is a local oscillator and signal combiner module for the 70000 Series Modular Measurement System (MMS) mainframe. It combines multiple RF signals into a single output while maintaining signal integrity, minimizing insertion loss, and reducing inter-channel interference. The module supports two independent RF inputs and one combined RF output, making it ideal for applications requiring precise signal mixing, parallel device testing, and multi-source RF characterization.
