3. Initial Setup

3.1. Charging the Device

1. Connect the provided Type-C data cable to the SA5's Type-C port.
2. Connect the other end of the cable to a compatible USB power adapter (not included) or a computer's USB port.
3. The device will indicate charging status on the display. A full charge provides approximately 10 hours of operation.

3.2. Powering On/Off

• To Power On: Press and hold the power button located on the side of the device until the display illuminates.
• To Power Off: Press and hold the power button until the shutdown prompt appears, then confirm.

3.3. MicroSD Card Installation

The SA5 comes with a 32GB MicroSD card pre-inserted. If you need to replace or re-insert the card:

1. Locate the MicroSD card slot on the bottom of the device.
2. Gently push the existing card to eject it, or insert a new card with the contacts facing down until it clicks into place.

3.4. Connecting RF Accessories

For spectrum analysis or signal generation, connect the appropriate RF cables and antenna to the RF ports on the device. Ensure connections are secure.

4. Operating Instructions

The SA5 offers two primary modes of operation: Spectrum Analyzer and Signal Generator. Use the rotary knob and touch screen for navigation and parameter adjustment.

4.1. Spectrum Analyzer Mode

In this mode, the SA5 measures and displays the frequency spectrum of input signals.

• Frequency Range: The device operates from 0.1MHz to 800MHz. Activate "Ultra mode" to extend the range up to 5.3GHz with level calibration, and monitor signals up to 12GHz.
• Resolution Bandpass Filter (RBW): Adjust the RBW from 200Hz to 850kHz to control the frequency resolution and noise floor.
• Input Attenuator: Use the step attenuator (0dB to 31dB) to prevent signal overload. Note that the attenuator cannot be used simultaneously with the Low Noise Amplifier (LNA).
• Optional LNA: The built-in 20dB LNA can be enabled to amplify weak signals.
• Spectrum Display: The display can show up to 450 points and supports up to 4 independently configured trace curves for detailed analysis.

4.2. Signal Generator Mode

When not used as an analyzer, the SA5 can generate various test signals.

• Sine Waves: Output sine waves from 0.1MHz to 800MHz.
• Square Waves: Generate square waves up to 4.4GHz.
• RF Test Signals: Output RF test signals up to 5.3GHz.

4.3. Calibration

The SA5 includes a built-in calibration signal generator. This allows for automatic self-testing and input calibration to ensure measurement accuracy. Refer to the on-screen menu for calibration procedures.

4.4. Data Storage and PC Connection

• Data Storage: Measurement data, device settings, and screenshots can be saved directly to the inserted MicroSD card.
• PC Connection: Connect the SA5 to a computer via the USB Type-C cable. The device can function as a PC-controlled spectrum analyzer or signal generator, and allows for convenient data transfer.

5. Maintenance

5.1. Cleaning

• Wipe the device exterior with a soft, dry cloth.
• For stubborn dirt, use a slightly damp cloth with mild soap, then wipe dry immediately.
• Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the display and casing.

5.2. Battery Care

• Avoid fully discharging the battery frequently.
• Charge the device regularly, even if not in use, to maintain battery health.
• Store the device in a cool, dry place when not in use for extended periods.

5.3. Storage

When storing the SA5, ensure it is powered off and kept in a protective case to prevent physical damage. Avoid extreme temperatures and high humidity.

6. Troubleshooting

6.1. Device Does Not Power On

• Ensure the battery is charged. Connect the device to a power source using the Type-C cable and allow it to charge for at least 30 minutes.
• Verify that the power button is pressed and held correctly.

6.2. Display Issues

• If the display is dim, check the brightness settings in the device menu.
• If the screen is unresponsive, try restarting the device.

6.3. Inaccurate Readings

• Perform a calibration using the built-in calibration signal generator (refer to Section 4.3).
• Ensure RF cables and connectors are securely attached and not damaged.
• Check the input attenuator settings to prevent signal overload.
• Verify that the correct frequency range and resolution bandwidth are selected for your measurement.

6.4. PC Connection Issues

• Ensure the Type-C cable is properly connected to both the SA5 and the computer.
• Verify that the necessary drivers (if any) are installed on your computer.
• Try a different USB port or cable.
