The Keysight (Agilent) N4413A Balanced Measurement S-parameter Test Set characterizes fully balanced and balanced-to-single-ended RF components across 50 MHz to 6 GHz. It extends Vector Network Analyzer capabilities to measure differential filters, amplifiers, baluns, and balanced transmission lines—devices that present measurement challenges in conventional two-port configurations. The system integrates a compatible VNA, external PC, and dedicated software to deliver full four-port vector error correction and mixed-mode S-parameter analysis.
