Upgraded 5.3 GHz Spectrum Analyzer
The BFKK TinySA Ultra is a handheld spectrum analyzer covering 100 kHz to 5.3 GHz with a 4.0 inch 480 x 320 touchscreen. It doubles as a signal generator offering sine output to 800 MHz and square or dual-tone output to 4.4 GHz. A built-in 32 Gb micro SD card stores captured data directly. Firmware version 0.4.5.1 adds ESD protection for longer service life.
Verify Power and Connector Needs
The unit charges via a USB Type-C cable and reaches full charge in about three hours. Confirm you have a suitable Type-C power source for field use. The RF input and generator output use standard SMA connectors; ensure your cables and adapters match. No external computer is required for basic operation, though PC software is available for advanced analysis.
Replaces 960 MHz Handheld Analyzers
Compared with the 2.8 inch model limited to 960 MHz, this Ultra extends measurement to 5.3 GHz and adds the generator function. The larger 450-point color display and switchable 200 Hz to 850 kHz resolution filters improve accuracy. Buyers who need real-time tracking above 6 GHz or built-in tracking generator output beyond 4.4 GHz should consider bench-top instruments instead.

Questions about this item
What comes in the box and do I need to buy a micro-SD card separately?
The unit ships with a 4.0 inch touchscreen, a Type-C charging cable and a built-in 32Gb micro-SD card already installed, so no separate card purchase is required.
Which frequency-range version should I choose for work up to 5.3 GHz?
This model covers 100 kHz to 5.3 GHz in spectrum-analyser mode and adds an ultra mode reaching 0.1 MHz to 6 GHz, so it handles the full 5.3 GHz span without needing a different variant.
How does the 450 scan-point display perform when measuring a wide 5.3 GHz span?
The 480 x 320 screen renders 450 points across the entire selected span, giving a clear spectral view whether you are scanning a narrow band or the full 5.3 GHz range.
