Operating Instructions
1. User Interface and Navigation
The TinySA Ultra+ ZS406 features a 4.0-inch touchscreen for intuitive operation. Use the included stylus or your finger to navigate menus and adjust settings. The main display shows the spectrum analysis or signal generation parameters.
2. Spectrum Analyzer Mode
In spectrum analyzer mode, the device measures frequencies from 100 kHz to 5.4 GHz. An 'Ultra' mode extends this capability up to 6 GHz. The color display can show up to 450 points, providing continuous coverage across the frequency range.
- Resolution Bandwidth (RBW): The RBW can be configured from 200 Hz to 850 kHz. A lower RBW (e.g., 200 Hz) allows for better distinction of adjacent signals, meeting requirements for SSB dual satellite intermodulation tests.
- Low Noise Amplifier (LNA): The LNA function, located in the level menu, provides an additional 20 dB of gain for very low-level signals. Note that the LNA in TinySA Ultra+ is effective only below 3.5 GHz.
- Phase Noise: The device exhibits excellent phase noise characteristics, with -92 dBc @ 10 kHz offset.
- Displayed Average Noise Level (DANL): -153 dBm/Hz (LNA Off) and -169 dBm/Hz (LNA On).

3. Signal Generator Mode
When not used as a spectrum analyzer, the device functions as a signal generator:
- MF/HF/VHF Sine Output: Generates sine waves between 100 kHz and 900 MHz.
- UHF Square Wave Output: Generates square waves between 800 MHz and 4.4 GHz.
- Mixed Signal Output: Provides mixed signals between 4.4 GHz and 5.4 GHz.
A built-in calibration signal generator is available for automatic self-testing and low input calibration.

4. PC Control and Data Transfer
The TinySA Ultra+ ZS406 can be connected to a PC via its USB Type-C port. The USB interface implements the Serial over USB (CDC) protocol, allowing for a range of commands to be invoked for measurements or internal setting updates.
- TinySA App: Use the dedicated TinySA application to transfer data directly to your computer, update firmware, and synchronize the device display with your PC.
- Driver Installation: For Windows PCs, the necessary drivers are installed automatically upon connection. For Linux, the controller is integrated into the kernel.

Maintenance
1. Battery Care
To prolong the life of the 5000 mAh Li-polymer battery, avoid fully discharging it frequently. Recharge the device when the battery level is low. Store the device in a cool, dry place if not used for extended periods.
2. Cleaning
Clean the device and its touchscreen with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents, as these can damage the screen and casing.
3. Firmware Updates
Periodically check for firmware updates to ensure optimal performance and access to new features. Firmware updates can be performed via the PC control application. Follow the instructions provided with the firmware update package carefully.
Troubleshooting
1. Device Not Powering On
- Ensure the battery is charged. Connect the device to a power source using the USB Type-C cable and allow it to charge for at least 30 minutes.
- Press and hold the power button firmly for a few seconds.
2. PC Connection Issues
- Verify that the USB Type-C cable is securely connected to both the device and the PC.
- Ensure the correct drivers are installed on your PC. For Windows, they should install automatically. For Linux, ensure the kernel has the necessary CDC ACM support.
- Try a different USB port or cable.
3. Inaccurate Measurements
- Perform a self-test using the built-in calibration signal generator.
- Ensure all cables and connectors are properly attached and in good condition.
- Check the RBW settings; a higher RBW might obscure fine details.
- Consider external interference if measurements are inconsistent.
