The Keysight N4432A is a 4-port electronic calibration (ECal) module that delivers NIST-traceable calibration accuracy across 300 kHz to 18 GHz. This solid-state instrument eliminates the need for mechanical calibration kits, reducing connector wear, repair costs, and operator-dependent errors. Single-connection calibration technique on 3- or 4-port configurations transfers factory calibration accuracy directly to Keysight PNA, ENA, PXI VNA, FieldFox, and USB vector network analyzers via USB control interface.
