The Keysight 70611A is an Attenuator-Switch Driver module engineered for integration within the Keysight 70000 series modular measurement system. It provides signal attenuation and switching control across distributed RF and microwave signal paths, capable of driving up to 248 external devices. This single-slot module communicates with the mainframe via the Modular Signal Switching (MSS) bus for high-speed digital control or GPIB for computer-based instrument control, enabling precise signal path management in spectrum analyzers and complex test configurations.
