4. Setup

1. Charging the Device: Connect the SA5 to a power source using the provided USB Type-C data cable. The device has a built-in 5000mAh battery.
2. Inserting MicroSD Card: If you wish to store measurement data, settings, or screenshots, insert a compatible MicroSD card (not included) into the designated slot.
3. Connecting Antennas/Cables: For RF signal analysis or generation, attach the appropriate antenna or RF cable to the SMA connectors on the device. Use the SMA-SMA barrel connector if needed for specific setups.
4. Power On: Press and hold the power button to turn on the device. The 4-inch IPS LCD will illuminate.
5. Initial Calibration: It is recommended to perform an initial calibration using the built-in signal generator for optimal accuracy. Refer to the 'Operating Instructions' for details.

5. Operating Instructions

5.1 General Operation

The SA5 features a 4-inch IPS LCD with touch functionality and a rotary knob for navigation and parameter adjustment. Use the touch screen for direct selection and the knob for fine-tuning values or scrolling through menus.

5.2 Spectrum Analyzer Mode

• Frequency Range: The standard operating range is 0.1-800MHz. To extend the range, enable 'Ultra mode' to calibrate signals up to 5.3GHz and monitor signals up to 12GHz.
• Resolution Bandpass Filter (RBW): Adjust the RBW from 200Hz to 850kHz to control the frequency resolution and noise level of the measurement. A narrower RBW provides higher frequency resolution but takes longer to sweep.
• Low Noise Amplifier (LNA): The optional 20dB LNA can be activated to improve the sensitivity for very weak signals. Note that the input attenuator cannot be used simultaneously with the LNA.
• Input Attenuator: Use the adjustable step attenuator (0dB to 31dB) to prevent overloading the input for strong signals.
• Display Interpretation: The display shows up to 450 points and can plot 4 independently configured curves, allowing for detailed analysis of complex RF environments.

5.3 Signal Generator Mode

When not in spectrum analyzer mode, the SA5 can function as a signal generator:

• Sine Wave Output: Generate sine waves across the 0.1-800MHz range.
• Square Wave Output: Produce square waves up to 4.4GHz.
• RF Test Signal Output: Generate RF test signals up to 5.3GHz for testing other equipment.

5.4 Data Management and PC Connection

• Saving Data: Use the MicroSD card slot to save measurement data, device settings, and screenshots.
• PC Control: Connect the SA5 to a computer via the USB Type-C port. The device can then be controlled by PC software, acting as an external spectrum analyzer or signal generator. This also facilitates easy transfer of stored data.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device, especially the screen. Avoid abrasive cleaners or solvents.
• Battery Care: To prolong battery life, avoid completely discharging the 5000mAh battery frequently. Charge the device regularly using the provided Type-C cable.
• Storage: Store the SA5 in a cool, dry place away from direct sunlight and extreme temperatures.
• Input Level: Always ensure that the input signal level does not exceed 10dBm to prevent permanent damage to the device.

7. Troubleshooting

• Device Not Powering On: Ensure the battery is sufficiently charged. Connect the device to a power source using the USB Type-C cable and try again.
• Inaccurate Readings: Perform a calibration using the built-in signal generator. Check all cable connections for proper seating. Ensure the correct frequency range and resolution bandwidth settings are applied for your measurement.
• PC Connection Issues: Verify that the USB Type-C cable is securely connected to both the SA5 and the computer. Ensure necessary drivers (if any) are installed on your PC.
• Screen Unresponsive: If the touch screen is unresponsive, try restarting the device. If the issue persists, use the rotary knob for navigation.
