Agilent/Keysight N2002A

The Agilent/Keysight N2002A Noise Source Test Set is a specialized calibration instrument designed to minimize uncertainty in noise figure measurements by accurately characterizing noise sources under test. Operating across 10 MHz to 26.5 GHz, this stand-alone module delivers fast, repeatable calibrations with results traceable to national standards, enabling tighter DUT specifications and increased measurement confidence.

Technical Specifications

• Frequency Range: 10 MHz to 26.5 GHz


• Control Interface: Manual or remote operation via GPIB


• Calibration Traceability: National standards


• System Integration: Operates with Agilent 11713A Attenuator/Switch Driver


• Operating Environment: Indoor use only

Key Features

• Isolation between noise source under test and measurement equipment, critical for repeatability


• Automated ENR (Excess Noise Ratio) and reflection coefficient measurements via dedicated software


• Supports manual and remote GPIB control for flexible operation


• Reduces measurement uncertainty through precision calibration methodology


• In-house calibration capability eliminates external laboratory dependencies

Typical Applications

• Calibration of Agilent SNS and 346 series noise sources


• Third-party noise source calibration across operating frequency range


• Noise figure measurement validation and uncertainty reduction


• Laboratory-based ENR testing and characterization

Compatibility & Integration The N2002A integrates with the Agilent 11713A Attenuator/Switch Driver for instrument control. Dedicated software automates complex ENR and reflection coefficient measurements. High-quality, precision-grade cables and adapters specified for the 10 MHz–26.5 GHz range and maintained in good condition are required for optimal performance. The test set accommodates noise sources from multiple manufacturers operating within its frequency range. Note: This product is obsolete with no identified direct replacement.
