Agilent/Keysight N4697K

The Agilent/Keysight N4697K is an electronic calibration (ECal) module designed to automate VNA calibration procedures. It delivers traceable, repeatable calibration performance while significantly reducing calibration time compared to mechanical kits. The module operates at 50 Ohms nominal impedance and supports full two-port calibration methods including SOLT (Short, Open, Load, Through) and transmission line calibration.

Technical Specifications

Product Type: Electronic Calibration (ECal) Module Impedance: 50 Ohms nominal Calibration Methods:

• Full two-port calibration (SOLT)


• Transmission Line (TL) calibration


• Specialized calibration types as supported by host VNA Data Interface: USB or specialized VNA interface for automated control

Key Features

• Eliminates manual calibration intervention and associated errors


• Provides traceable calibration standards with repeatable performance


• Compact, all-in-one solution reducing setup complexity


• Significantly faster than traditional mechanical calibration kits

Typical Applications The N4697K serves R&D environments, manufacturing test floors, and field service operations where accurate and efficient VNA calibration is essential. Its automation capabilities minimize downtime and human error in high-throughput testing scenarios.

Compatibility & Integration The module integrates with VNAs through USB or dedicated control interfaces. RF connection to the VNA's test ports uses standard connectors. Return loss and insertion loss performance of internal standards (Short, Open, Load, Through) define calibration accuracy specifications. The module's compact form factor suits both benchtop and portable deployment models.
