Call 0345 2300 599The RF Explorer RFEM4G PLUS is an expansion module designed to convert a compatible RF Explorer WSUB1G PLUS into a powerful 4G Combo PLUS Spectrum Analyser.
When installed with a compatible WSUB1G PLUS model, the RFEM4G PLUS allows coverage from 50kHz up to 4GHz with no gaps or limitations. A future firmware licence will also allow the range to be expanded up to 5.1GHz without the need for additional hardware.
This makes it an excellent choice for amateur radio, RF testing, Wi-Fi analysis, interference hunting, EMC pre-testing, and general RF spectrum monitoring.
Compatibility Note
The RF Explorer RFEM4G PLUS is an expansion board for RF Explorer WSUB1G PLUS models.
It can be assembled in:
- RF Explorer WSUB1G PLUS
- RF Explorer WSUB1G PLUS SLIM
This listing is for the RFEM4G PLUS expansion module only. A compatible RF Explorer WSUB1G PLUS analyser is required.
