Keysight (Agilent) N7553A Electronic Calibration Module (ECal), DC-14 GHz, 2-Port

The Keysight N7553A is a 2-port electronic calibration module (ECal) that automates vector network analyzer calibration from DC to 14 GHz. It replaces mechanical calibration kits with a single-connection, fully automated process controlled via USB 2.0 micro-interface by the host instrument’s firmware. The N7553A delivers approximately 50% faster calibration cycles than traditional methods, with zero wait time between measurements, while maintaining high measurement accuracy and repeatability.
