Operating Instructions
The NXT-1000 extends the capabilities of your EtherScope nXG for detailed Wi-Fi spectrum analysis.
Performing a Spectrum Scan
- Access Spectrum Analysis: On your EtherScope nXG, open the "Spectrum Analysis" or "Wi-Fi Spectrum" application.
- Select Frequency Band: Choose between 2.4GHz or 5.0GHz band for analysis, depending on your requirements.
- Start Scan: Initiate the scan. The NXT-1000 will begin collecting RF data.
- Interpret Results: The EtherScope nXG display will show real-time spectrum data, including channel utilization, interference sources, and signal strength. Pay attention to areas of high noise or overlapping channels.
Understanding Spectrum Graphs
The spectrum graph typically displays amplitude (dBm) versus frequency (GHz). Peaks indicate active signals, while a high noise floor suggests interference. Different colors or patterns may represent various types of interference or channel usage.

Best Practices for Analysis
- Perform scans in various locations within your environment to identify localized interference.
- Identify non-Wi-Fi interference sources (e.g., microwave ovens, cordless phones) by observing their unique spectrum signatures.
- Use the data to optimize Wi-Fi channel selection and troubleshoot connectivity issues.
Maintenance
- Cleaning: Use a soft, dry, lint-free cloth to clean the exterior of the NXT-1000. Do not use liquid cleaners or abrasive materials.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. When not in use, it is recommended to disconnect it from the EtherScope nXG.
- Antenna Care: Handle the antenna carefully to avoid bending or damaging it. Ensure it is securely attached during use.
- Firmware Updates: Regularly check for firmware updates for your EtherScope nXG, as these may include enhancements or bug fixes related to the NXT-1000's functionality.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| NXT-1000 not detected by EtherScope nXG. | Loose USB connection, outdated EtherScope nXG firmware, damaged NXT-1000. | Ensure the USB connection is secure. Update EtherScope nXG firmware. Try connecting to a different USB port if available. If issues persist, contact NetAlly support. |
| Inaccurate or no spectrum data. | Improper antenna orientation, high environmental noise, device malfunction. | Adjust antenna position for optimal reception. Move to a less noisy environment if possible. Ensure no physical obstructions are blocking the antenna. |
| Device gets unusually warm. | Extended use, poor ventilation. | This is normal during operation. Ensure the device is not covered and has adequate airflow. If it becomes excessively hot or exhibits abnormal behavior, disconnect it and contact support. |
