Let radio enthusiasts enter the SDR era and experience spectrum visualization—both hearing and seeing signals. This SDR receiver functions as both a receiver and a spectrum analyzer, with performance comparable to traditional hardware spectrum analyzers. It features a 7-inch tablet computer powered by an Intel low-power quad-core processor. The device offers over 3 hours of continuous operation on a full charge. It operates as an RF analyzer and broadband spectrum analyzer compatible with Android and HarmonyOS. Frequency range: 25 MHz to 1896 MHz. With optional extensions, it supports medium wave (MW) and shortwave (HF), as well as VHF and UHF bands. It receives AM, FM (WFM/NFM), and SSB (USB/LSB) signals. Applications include monitoring broadcast stations, marine radio, coast radio, amateur radio, civil aircraft communications, two-way radios, wireless microphones, remote controls, and more. It is ideal for signal analysis—including presence, strength, bandwidth, modulation type—as well as identifying co-channel and adjacent-channel interference. It supports field assessments of wireless microphone frequencies and interference detection. It also enables monitoring of VHF/UHF two-way radios, remote controls, and key fobs operating at frequencies such as 315 MHz and 433 MHz. Appearance may vary by production batch.
