## Details

### Configuration

- Option 800: Standard Frequency Reference

## Function

Performs precision impedance measurements including capacitance, inductance, resistance, reactance, dissipation factor, and quality factor across 40Hz to 110MHz frequency range. Features 0.08% basic accuracy, 4-terminal pair configuration for precise measurements, and integrated DC bias capability up to ±40V or ±100mA. Supports multiple measurement parameters displayed simultaneously with real-time analysis. Interfaces via GPIB, RS-232, and handler port for automated test systems. Built-in equivalent circuit analysis determines component models. Commonly used for characterizing passive components, materials testing, semiconductor device analysis, and production testing of RLC components, filters, and resonators.
