Agilent/Keysight N4416A

The Agilent/Keysight N4416A is a balanced measurement S-parameter test set engineered for use with Keysight PNA Series Vector Network Analyzers to characterize RF and microwave components across 300 kHz to 6 GHz. It enables measurement of single-ended and mixed-mode S-parameters, making it suitable for analyzing balanced or balanced-to-single-ended RF components and high-speed digital interconnects.

Technical Specifications

• Frequency Range: 300 kHz to 6 GHz


• Measurement Parameters: Single-ended and mixed-mode S-parameters


• Error Correction: Full four-port vector error correction


• Data Renormalization: Support for non-50-ohm device impedance

Key Features

• Automatic calibration with the optional N4430A four-port electronic calibration (ECal) module


• User-defined parameter displays for custom calculations


• Time-domain analysis capability


• Fast, accurate calibration procedures

Typical Applications

• Characterization of balanced RF and microwave components


• Mixed-mode S-parameter measurement of balanced-to-single-ended devices


• High-speed digital interconnect analysis


• Non-50-ohm device impedance characterization

Compatibility & Integration The N4416A integrates with Keysight PNA Series VNAs - specifically the E8356A, E8357A, or E8358A with Option 015 - and requires an external PC with IEEE-488 GPIB connectivity. Operation requires either the N4425A Balanced Measurement System software or the N1930A Physical Layer Test System software for control, calibration, data display, and analysis. The test set supports the N4430A four-port electronic calibration module for streamlined calibration workflows. Note: This product is obsolete. The N4416A test set itself is not subject to calibration testing; performance characteristics are factory-verified. Functional testing can validate proper operation of all microwave components within the test set.
