4. Інструкцыя па эксплуатацыі
The ZA-048 antenna is designed for radio direction finding and general spectrum analysis within its specified frequency range.
- Дыяпазон частот: The antenna operates effectively from 400MHz to 8GHz. For optimal directionality, use within the 1GHz to 8.5GHz range.
- Directional Use: When performing radio direction finding, orient the antenna towards the suspected signal source. The antenna exhibits decent sensitivity for identifying signal source direction, especially when held and rotated.
- Spectrum Analyzer Settings: Configure your spectrum analyzer according to the desired frequency band and measurement parameters. Ensure the input impedance setting matches the antenna's 50Ω impedance.
- Signal Strength Observation: Observe the signal strength readings on your spectrum analyzer. Peak readings indicate the direction of the strongest signal.
