The N4421B is a S-parameter Test Set. The N4421B S-parameter test set is a key component of an Agilent physical layer and balanced-measurement system.
When combined with a vector network analyzer and an external PC equipped with an IEEE-488 GPIB card, this test set makes characterizing high-speed digital interconnected as well as, fully balanced or balanced-to-single-ended RF components a lot easier.
Combining a unique multi-port hardware architecture with a fast multiple-term calibration algorithm, the multi-port test system provides true multi-port vector error-correction while preserving the accuracy of the underlying network analyzer.
