2. Características clave

2-wire Impedance Analyzer: Integrates directly with the Impedance Analyzer tool in WaveForms.
Capacitance Measurement Range: 50pF to 500µF.
Inductance Measurement Range: 10µH to 1000mH.
Excitation Frequency Range: 1Hz to 15MHz.
Requisitos de software: Requires WaveForms version 3.8.2 or later for operation.

3. Instrucións de configuración

Instalación de software: Ensure you have WaveForms software version 3.8.2 or later installed on your computer. If not, download and install the latest version from the Digilent websitio.
Connect Analog Discovery: Connect your Analog Discovery device (Analog Discovery 2 or Analog Discovery Legacy) to your computer via USB.
Attach Impedance Analyzer: Carefully align and connect the Digilent Impedance Analyzer module to the 2×15 connector on your Analog Discovery device. Ensure a secure connection.
Launch WaveForms: Open the WaveForms software. The software should detect the connected Analog Discovery device and the Impedance Analyzer accessory.
Access Impedance Analyzer Tool: Navigate to the Impedance Analyzer tool within the WaveForms software interface.

4. Instrucións de funcionamento

The Impedance Analyzer accessory is designed for ease of use with the WaveForms software. It automatically adjusts reference resistors and relays to select the most appropriate configuration for the unknown impedance being measured.

Connect Device Under Test (DUT): Connect the component or circuit you wish to analyze to the input terminals of the Impedance Analyzer module.
Configure Settings in WaveForms: Within the WaveForms Impedance Analyzer tool, select your desired excitation frequency range and measurement parameters. The accessory will automatically adapt its internal configuration.
Iniciar a medición: Start the measurement process in WaveForms. The software will display the impedance characteristics of your DUT.
Analizar resultados: Use the plotting and analysis features within WaveForms to interpret your measurement data, including impedance magnitude, phase, capacitance, and inductance.

5. Mantemento

The Digilent Impedance Analyzer is a robust device designed for durability. Minimal maintenance is required.

Limpeza: Use a soft, dry cloth to gently clean the module. Avoid using liquid cleaners or solvents, as these can damage the electronic components.
Almacenamento: Store the module in a dry, dust-free environment when not in use. Protect it from extreme temperatures and humidity.
Manexo: Handle the module by its edges to avoid touching the electronic components directly.

6 Solución de problemas

If you encounter issues with your Impedance Analyzer, consider the following:

Módulo non detectado: Ensure the Impedance Analyzer is securely connected to the Analog Discovery device and that the Analog Discovery device is properly connected to your computer and recognized by WaveForms.
Versión de software: Verify that your WaveForms software is version 3.8.2 or later. Older versions may not support the Impedance Analyzer accessory.
Problemas de conexión: Check all cable connections. Ensure the Analog Discovery device is receiving power.
Lecturas incorrectas: Ensure the Device Under Test (DUT) is correctly connected to the module's terminals. Review the settings in the WaveForms Impedance Analyzer tool.
Software Restart: Sometimes, restarting the WaveForms software or your computer can resolve minor communication issues.
