Portable spectrum analyzer 100 kHz–960 MHz

The Seesii TinySA V3.1 is a handheld spectrum analyzer covering 100 kHz to 960 MHz with dual inputs for MF/HF/VHF and UHF ranges. It includes a built-in signal generator and a 2.8 inch touch screen for direct control. The 2024 version 3.1 adds ESD protection for improved durability.

Frequency coverage and resolution limits

The MF/HF/VHF input handles 0.1 MHz to 350 MHz while the UHF input covers 240 MHz to 960 MHz. Switchable resolution bandpass filters operate between 2.6 kHz and 640 kHz across both ranges. A color display presents 290 scan points spanning the selected frequency span.

ESD-protected version 3.1 stability

The 2024 V3.1 hardware revision delivers more stable and sensitive performance with a new ESD protected function that raises antistatic resilience and extends service life. This specific upgrade is the deciding factor for users who need reliable operation in static-prone environments.

Questions about this item

Will the 100 kHz–960 MHz range let me measure signals from my older MF/HF/VHF gear?

Yes, the high-quality MF/HF/VHF input covers 0.1 MHz to 350 MHz and the UHF input covers 240 MHz to 960 MHz, so legacy equipment in those bands can be analysed directly.

How do I verify the analyser is working correctly after I connect it?

Run the built-in self-test using the internal calibration signal generator; it automatically checks the low input and confirms the 290-scan-point display and switchable 2.6–640 kHz filters are operating as expected.

What comes in the box and what must I buy separately for PC control?

The handheld unit with integrated rechargeable battery and 2.8 inch touch screen is included; a standard USB cable for CDC serial connection to a PC is not supplied and must be purchased separately.
