The Agilent 16085B is an adapter designed to convert the 4-terminal-pair (4TP) measurement configuration of HP/Agilent impedance instruments to an APC-7 coaxial interface. Its main function is to make it easy to connect specialized fixtures for the electrical characterization of discrete components and precision electronic devices.
This adapter is widely used in validation laboratories, component analysis, electronics development and quality testing, especially in applications where measurement errors caused by parasitic impedances, unstable connections or improvised adaptations must be reduced.
Compatibility with Measurement Fixtures
The 16085B terminal adapter allows the use of specialized fixtures for different electronic component geometries, including:
- Agilent 16092A
- Agilent 16093A
- Agilent 16093B
Thanks to this compatibility, the system can be quickly adapted to many types of devices under test without modifying the main instrument.
Principle of Operation
The adapter converts the high-precision 4-terminal-pair measurement architecture to a two-terminal APC-7 interface, maintaining low residual impedances and minimizing errors caused by:
- Residual inductance
- Parasitic capacitance
- Contact resistance
- Electromagnetic coupling
This type of configuration is especially important for measuring:
- Capacitor ESR
- Coil inductance
- Complex impedance
- RF component characterization
- Passive component validation
APC-7 connectors also preserve excellent electrical integrity in high-frequency measurements.
