Keysight / Agilent N4421A Overview

The Agilent N4421A S-parameter test set is a key component of an Agilent physical layer and balanced-measurement system. When combined with an Agilent PNA Series E8364B Option 014 vector network analyzer and an external PC equipped with an IEEE-488 GPIB card, this test set makes characterizing high-speed digital interconnects as well as, fully balanced or balanced-to-single-ended RF components much easier.

The N4421A S-parameter test set requires the N4425A Balanced Measurement System software or the N1930A Physical Layer Test System software for control of the 4-port VNA system, calibration, and data display and analysis.

Please note, this test set is not subject to a calibration test. The test set’s performance characteristics are parameters that the product is expected to meet before it leaves the factory. A functional test can verify proper performance of all microwave components within the test set.

Features:

• The following features apply to a complete balanced-measurement system:
• Display conventional (single-ended) and mixed mode S-parameters
• Re-normalize test data for non-50-ohm devices
• Achieve high measurement accuracy with full four-port vector error correction
• Calculate important parameters with powerful user-defined displays
• Gain additional insight with time domain analysis option
