The HP/Agilent 41951A Impedance Test Kit is a specialized accessory that extends the measurement capabilities of the HP 4195A Network/Spectrum Analyzer, enabling precise impedance characterization of electronic components and circuits. The kit supplies fixtures, adapters, and calibration standards necessary for accurate and repeatable measurements across diverse component types and test configurations, supporting both surface-mount and through-hole device testing.
## Technical Specifications
**Measurement Parameters**
The 41951A characterizes impedance (Z), admittance (Y), resistance (R), reactance (X), conductance (G), susceptance (B), inductance (L), capacitance (C), Q factor, and dissipation factor (D).
**Frequency Range**
10 Hz to 500 MHz, dictated by the HP 4195A Network/Spectrum Analyzer.
**Impedance Matching**
The test kit presents a known impedance of 50 ohms to the analyzer, minimizing reflections and measurement error.
## Key Features
• Primary test fixture designed to hold components and establish electrical connections for measurement
• Component holders for surface-mount devices (SMDs) and through-hole configurations
• High-quality test leads for direct circuit and component connection
• Open/short/load calibration standards for systematic error compensation and setup calibration
• Dedicated connection ports to the HP 4195A for impedance test signal routing
## Typical Applications
Component design and characterization, quality control testing, and impedance profiling across the 10 Hz to 500 MHz frequency span. The kit supports development and validation workflows requiring multi-parameter impedance analysis.
## Compatibility & Integration
The 41951A is exclusively designed for use with the HP 4195A Network/Spectrum Analyzer. Performance and functionality depend entirely on the connected analyzer’s capabilities.
