3. Setup
Before first use, it is recommended to fully charge the device using the supplied USB-C cable. The TinySA features two input ports for different frequency ranges:
- MF/HF/VHF Input: For frequencies from 0.1MHz to 350MHz.
- UHF Input: For frequencies from 240MHz to 960MHz.
Connect the appropriate antenna or RF cable to the desired input port based on the frequency range you intend to analyze or generate. The device is operated via its 2.8-inch resistive touchscreen using the included stylus or finger.

3.1 Initial Calibration
For accurate measurements, perform a level calibration. Connect the high and low SMA connectors using a small SMA cable (supplied). Navigate to the 'Config' menu and select 'Level Calibrate'. Follow the on-screen instructions to complete the calibration process.
3.2 PC Control Setup
The TinySA can be controlled via a PC using the USB interface, which implements the Serial over USB (CDC) protocol. A Windows driver will automatically install upon connecting to a Windows PC. For Linux, the driver is built into the kernel. The TinySA-APP is available to control the device and capture its screen for more detailed analysis.

4. Operating Modes
The TinySA operates in various modes, functioning as both a spectrum analyzer and a signal generator. The device includes all components of a traditional heterodyne swept spectrum analyzer.
4.1 Spectrum Analyzer Mode
In this mode, the device displays frequency spectrums. It features switchable resolution bandpass filters for both ranges (2.6kHz to 640kHz). The color display shows 290 scan points covering up to the full low or high frequency range.

4.2 Signal Generator Mode
When not used as a spectrum analyzer, the TinySA can function as a signal generator:
- MF/HF/VHF Sinus Output: Generates sine waves between 0.1MHz and 350MHz.
- UHF Square Wave Output: Generates square waves between 240MHz and 960MHz.
A built-in calibration signal generator enables automatic self-test and low input calibration.
