The SeeSii TinySA Ultra+ ZS406 is a compact, handheld spectrum analyzer designed for fast, accurate RF work in the field or lab. It covers 100 kHz to 5.4 GHz (Ultra mode up to 6 GHz), adds ESD protection for better reliability, and logs data directly to the included 32 GB micro-SD card. Use it as a portable spectrum analyzer for MF/HF/VHF/UHF and microwave checks—or switch to signal-generator mode for quick bench setups and calibration. PC users can connect by USB for full PC-controlled spectrum analyzer operation and scripted measurements. This kit also includes the ZK06-UM 21 dB low-noise amplifier (LNA)—a USB-C powered module with broadband coverage that boosts weak signals without adding much noise, perfect for antenna and receiver testing.
