The device features an intuitive layout with an On/Off button, an indicator light, a multi-functional knob for navigation, a Type-C USB interface for charging and data, a 3.5mm audio jack, and a convenient SD card slot for the included 32GB micro SD card.

Setup

1. Initial Charging: Before first use, fully charge the TinySA Ultra using the provided USB-C cable. Connect it to a standard USB power adapter (not included) or a computer's USB port. The indicator light will show charging status.
2. SD Card Installation: The 32GB micro SD card is typically pre-installed. If not, gently insert it into the SD card slot until it clicks into place. Ensure the device is powered off before inserting or removing the SD card.
3. Connecting Antennas/Cables: For spectrum analysis, connect the appropriate antenna or RF cable to the "RF" input port. For signal generation, connect your load or measurement device to the "CAL" output port.
4. Power On: Press and hold the On/Off button until the screen illuminates.

Operating Instructions

Basic Navigation

• Touchscreen: Navigate menus and adjust settings by tapping on the 4-inch touch screen.
• Multi-functional Knob: Rotate the knob to scroll through options or adjust values. Press the knob to select an option or confirm a setting.

Spectrum Analyzer Mode

1. Selecting Mode: From the main menu, select "Spectrum Analyzer" mode.
2. Setting Frequency Range: Adjust the start and stop frequencies to define your desired measurement range. The device supports 100kHz to 5.3GHz.
3. Resolution Bandwidth (RBW): Configure the RBW (200Hz to 850kHz) to optimize for signal separation or scan speed. A lower RBW provides better frequency resolution but slower scans.
4. LNA/DANL: Utilize the Low Noise Amplifier (LNA) for measuring very weak signals. Be aware of the Device Average Noise Level (DANL) for the sensitivity limits.
5. Measurements: The screen will display the spectrum. Use markers to identify specific frequencies and power levels.

Signal Generator Mode

1. Selecting Mode: From the main menu, select "Signal Generator" mode.
2. Output Type: Choose between sine wave (100kHz-800MHz), square wave (800MHz-4.4GHz), or mixing signal (4.4GHz-5.4GHz).
3. Frequency and Level Setting: Set the desired output frequency and amplitude level using the touchscreen or multi-functional knob.
4. Calibration Signal: The built-in calibration signal generator can be used for self-testing and low input calibration.

PC Control

• Connection: Connect the TinySA Ultra to your computer using the USB-C cable.
• Driver Installation: For Windows, the driver should install automatically. For Linux, the driver is built into the kernel.
• TinySA-APP: Download and install the TinySA-APP from the official website (tinysa.org) for advanced control, display synchronization, and data transfer.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Avoid abrasive cleaners or solvents.
• Battery Care: To prolong battery life, avoid fully discharging the device frequently. Store it with a partial charge if not used for extended periods.
• ESD Protection: The device has built-in ESD protection. However, always handle it with care and avoid static discharge, especially when connecting cables.
• Software Updates: Regularly check the official TinySA website (tinysa.org) for firmware updates to ensure optimal performance and access to new features.

Troubleshooting

• Device Not Powering On:

  Ensure the battery is charged. Connect to a USB power source and try again. If the issue persists, contact support.

• Inaccurate Readings:

  Perform a self-test and calibration as described in the device's on-screen menu or the TinySA-APP. Ensure correct antenna/cable connections and proper frequency range settings. Consider using external attenuators for high input signals to protect the device.

• PC Connection Issues:

  Verify the USB-C cable is securely connected. Try a different USB port or cable. Ensure the TinySA-APP is the latest version and drivers are correctly installed on your operating system.

• Difficulty Navigating Menus:

  Familiarize yourself with the multi-functional knob and touchscreen controls. Refer to online resources and community forums for detailed usage guides if needed, as the device has a significant learning curve for its advanced capabilities.
