Chelegance RF Explorer 6G Combo PLUS Slim Spectrum Analyser

The RF Explorer 6G Combo PLUS Slim is a pocket-sized spectrum analyser for monitoring and troubleshooting RF activity from 50kHz to 6.1GHz. Its two input paths provide gapless coverage across LF, MF, HF, VHF, UHF, amateur-radio and 2.4/5GHz Wi-Fi bands, making it well suited to interference hunting, signal monitoring, antenna work, leakage detection and EMC pre-testing.
