Keysight (Agilent) 16442B Test Fixture

The Keysight 16442B Test Fixture is a precision measurement interface designed for impedance characterization of leaded electronic devices. It provides stable, repeatable connections to LCR meters and impedance analyzers, enabling accurate component evaluation and quality control in production and laboratory environments. The fixture features comprehensive EMI shielding to ensure measurement integrity in standard operating conditions.

– Technical Specifications

Channel Configuration
• 6 SMU channels via triaxial connectors—configurable as 6 non-Kelvin or 3 Kelvin connections
• 2 VSU channels (BNC connectors)
• 2 VMU channels (BNC connectors)
• 2 PGU channels (BNC connectors)
• 1 GNDU channel (triaxial connector, requires Agilent 16493L cable)

Electrical Ratings
• SMU triaxial connectors: up to 200 V and 1 A DC

Connector Architecture
• 6 triaxial connectors (SMU and GNDU)
• 6 BNC coaxial connectors (VSU, VMU, PGU)
• 1 six-pin interlock connector for safety interlocks

Safety Interlock System
The Intlk terminal prevents electric shock during operation. Interlock verification requires connection between the 16442B Intlk terminal and the instrument’s interlock terminal, with voltage applied to confirm High Voltage LED activation and deactivation.

– Key Features

• Modular socket architecture supports multiple device packages: 28-pin and 18-pin DIP, 4-pin TO-package, and universal socket modules at 0.1 inch, 0.075 inch, and 0.05 inch pitch
• Comprehensive accessory kit including stabilizer set, connection pin set, and color-coded banana and pin plug cables
• Carrying case for organized socket module storage and transport
• Blank PTFE board for custom fixture development

– Compatibility & Integration

The 16442B integrates with Keysight instrumentation including the B1500A, B2900 Series, and E5260/E5270 Series parametric analyzers and LCR measurement systems.
