Pocket RF Analyser

The BFKK TinySA V3.1 is a handheld spectrum analyser covering 0.1 MHz to 350 MHz on the MF/HF/VHF input and 240 MHz to 960 MHz on the UHF input. It targets radio hobbyists, field technicians and students who need portable frequency-domain measurements without a bench instrument.

Dual-Role Signal Source

A built-in calibration generator performs automatic self-test and low-input calibration, then doubles as an independent signal source with MF/HF/VHF sine output up to 350 MHz and UHF square-wave output up to 960 MHz. The switchable resolution band-pass filter spans 2.6 kHz to 640 kHz for flexible selectivity.

USB Control and Touch UI

The 2.8-inch colour touch screen renders 290 scanning points across the full span, while a USB link exposes a CDC serial interface for PC automation on Windows or Linux. A 650 mA rechargeable battery supplies at least two hours of operation, and version 3.1 adds diode-based ESD protection for rugged field use.
