Handheld Spectrum Analyser 100 kHz-960 MHz

The WUQ TinySA V0.3.1 is a portable test instrument that combines a spectrum analyser and a signal generator in one pocket-sized unit. It covers MF, HF, VHF and UHF bands with two dedicated inputs and a 2.8 inch colour touchscreen showing 290 scan points. The firmware is updatable and the device includes ESD protection diodes for improved longevity. A built-in 500 mAh battery powers the unit for field work.

RF engineers, hobbyists

This analyser suits users who want a compact tool for quick signal checks, antenna tuning or teaching demonstrations up to 960 MHz. It is not for buyers who need laboratory-grade dynamic range, phase-noise performance or calibrated absolute amplitude accuracy. It is not for applications requiring continuous wave output above 350 MHz or resolution bandwidths narrower than 2.6 kHz. It is not for users who must operate without a PC for advanced automation.

Check SMA connectors, USB-C power

Before ordering, verify that your test leads and antennas use SMA connectors compatible with the supplied cables and adapters. Confirm you have a USB-C cable for charging the internal battery and for PC control over the CDC serial interface. Ensure your computer runs Windows with automatic driver installation or Linux with the kernel driver already present. The Tinysa-APP software is required for screen capture and remote operation.

Questions about this item

What PC interface is required to control the TinySA V0.3.1 from a computer?

The USB-C port implements Serial over USB (CDC); on Windows the driver installs automatically, while on Linux the CDC driver is already in the kernel, so a standard USB-C cable is all that is needed.

Can the UHF input on this analyser measure signals below 240 MHz alongside my existing HF equipment?

No — the UHF input covers 240 MHz to 960 MHz, while the MF/HF/VHF input handles 100 kHz to 350 MHz, so frequencies below 240 MHz must use the MF/HF/VHF port.

How can I confirm the spectrum analyser is operating correctly after connecting it?

Enable the built-in calibration signal generator; it produces a sinus output up to 350 MHz and a square-wave output up to 960 MHz for automatic self-test and low-input calibration verification.
