Agilent/Keysight N4417A

The Agilent/Keysight N4417A is a solid-state electronic calibration (ECal) module that automates vector network analyzer calibration across 300 kHz to 9 GHz. It replaces mechanical calibration methods, enabling one-button operation with minimal operator interaction and eliminating manual error sources. The module acts as a transfer standard, applying factory-calibrated S-parameter data stored within its memory to compute VNA error terms and deliver consistent, traceable measurements.
