Agilent/Keysight N7555A

The N7555A is a 2-port electronic calibration module engineered to accelerate VNA calibration workflows across DC to 26.5 GHz. This value-line ECal accessory cuts calibration time approximately in half compared to traditional mechanical kits, delivering zero wait time for faster measurement setup. Communication and control occur via a single USB 2.0 micro-interface connection, eliminating the need for complex multi-step calibration procedures.

Technical Specifications

• Frequency Range: DC to 26.5 GHz


• Port Configuration: 2-port


• Connector Type: 3.5 mm (available in female, male, or mixed configurations)


• Interface: USB 2.0 micro-interface
