Tiny ultra spectrum analyzer

The device shown in the image is a tinySA Ultra Spectrum Analyzer, a portable and affordable tool primarily used for analyzing radio frequency (RF) signals and related electronic measurements.
What you can do with a tinySA Ultra Spectrum Analyzer:
RF Signal Analysis:
Measure Harmonics and Spectral Purity: Evaluate the unwanted frequencies present in a signal and its overall spectral cleanliness.
Measure Phase Noise and Third-Order Intermodulation: Assess the stability of a signal's phase and the distortion caused by multiple signals.
Capture ISM Transmissions: Monitor and analyze signals in Industrial, Scientific, and Medical (ISM) bands, commonly used for wireless devices like remote controls or surveillance systems.
Check Spurious Emissions: Identify and measure unintended RF emissions from electronic devices.
Monitor RF Interference: Track down sources of interference, such as those affecting wireless systems or radio communication.
Radio and Electronics Testing:
Test Receiver
