1.3 Initial Charging

Before first use, fully charge the device. Charging time is approximately 1 hour using a 500mA minimum USB port or USB charger. A fully charged battery provides at least 2 hours of operation.

2. Operating Instructions

2.1 User Interface and Display

The device features a 320x240 pixel, 2.8-inch 16-bit RGB resistive touch screen. Navigation is primarily via touch control and a jog switch. The display shows scan points covering the frequency range.

2.2 Frequency Range and Input Modes

The Tiny SA Spectrum Analyzer operates with two inputs:

• MF/HF/VHF Input: 0.1MHz - 350MHz (High quality)
• UHF Input: 240MHz - 960MHz (Lesser quality)

Switchable resolution bandpass filters are available for both ranges, between 2.6kHz and 640kHz. The fastest scanning speed is achieved with an RBW of 300kHz or wider, at approximately 2 scans per second. Scanning speed decreases with increased frequency span and decreased RBW.

2.3 Signal Generator Function

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

• MF/HF/VHF Sinus Output: 0.1MHz - 350MHz
• UHF Square Wave Output: 240MHz - 960MHz

It includes a built-in calibration signal generator for automatic self-test and low input calibration. An optional square wave output with a fundamental at -25dBm can be connected to the high input/output. Frequencies can be set to 1MHz, 2MHz, 4MHz, 10MHz, 15MHz, or 30MHz.

2.4 PC Control

The USB interface supports the Serial over USB (CDC) protocol, allowing for a range of commands to perform measurements or update internal settings. Drivers for Windows install automatically. Linux drivers are built into the kernel. Two software applications are available for PC control, both capable of capturing the device's screen.

2.5 Frequency Calibration

Frequency calibration ensures accurate measurements. This process involves measuring the internal reference frequency and applying a correction. The video below demonstrates how to perform frequency calibration using an external frequency counter.

2.6 High Input Level Calibration

Calibrating the high input level is crucial for accurate power measurements. This procedure typically involves using a known signal source and adjusting the device's settings. The video below illustrates the steps for high input level calibration.

2.7 Measurement Capabilities

The Tiny SA Spectrum Analyzer is capable of various measurements, including:

• Measuring Harmonics
• Measuring Spectral Purity
• Measuring Phase Noise
• Measuring Third Order Intermodulation
• Measuring IQ Balance
• Measuring Spur Free Dynamic Range
• Measuring Low Frequencies
• Capturing ISM Transmissions
• Tuning Sweep Settings
• Coax Cable Impact
• Measuring harmonic content of a transmitter
• Measuring FM deviation
• Measuring AM modulation
• Adding an LNA
• Using a Tracking Generator to measure a Mixer

3. Maintenance

3.1 Battery Care

The device uses a Lithium Ion battery. Ensure regular charging to maintain battery health. Avoid extreme temperatures. The battery is included and required for operation.

3.2 Firmware Updates

The firmware of the Tiny SA can be updated by the user. For the newest firmware version and update instructions, please refer to the official website: tinysa.org.

4. Troubleshooting

If you encounter issues with your Tiny SA Spectrum Analyzer, consider the following general troubleshooting steps:

• Power Issues: Ensure the device is fully charged. Check the USB connection if charging or connected to a PC.
• Display Problems: If the screen is unresponsive, try restarting the device. Ensure the touch screen is clean.
• Measurement Inaccuracies: Perform frequency and level calibrations as described in Section 2.5 and 2.6. Verify correct input/output mode selection.
• PC Connectivity: Ensure the USB cable is securely connected. For Windows, verify drivers are installed. For Linux, drivers are typically built-in.
• Unexpected Behavior: Consider performing a self-test (if available in the device menu) or updating the firmware to the latest version.

For persistent issues, consult the official Tiny SA website or contact customer support.
