Getting started with RF Explorer Spectrum Analyzer


Thanks for supporting this project with your order. We hope you received your unit in perfect condition and are ready to use it for the first time.

All documents, software downloads and firmware upgrade details are available from our download page (link). Make sure you visit it to get the best possible value from your instrument.

If you received a RF Explorer Signal Generator device, please visit the dedicated page at Getting Start with Signal Generator (link).

If you are like us, the first thing you want to do is to power up your unit and play with it. This is perfectly ok; just make sure you are not near any strong RF field before plugin in your antenna in the SMA connector. At very same instant you plug in the antenna, the device will start receiving RF energy even if it is powered off. This is not much of an issue if you are using a 6G Combo, a 3G Combo or WSUB1G PLUS, but some RF Explorer models like WSUB1G are protected from moderate RF signals only, not against very strong fields.

Please read this article for more details on how to protect your device from strong RF fields (link). Failing to do so may damage your RF Explorer.


This is a battery operated device, please charge the battery fully before use; it comes with half charge as the standard way to extend the battery life when it is stored for an undetermined period of time on the warehouse. But to use it you should fully charge it. Never charge your device unattended. Important: if you are using a RF Explorer WSUB1G PLUS model and comes with firmware v3.03 or earlier, the initial battery level may display too low. By following the full charge and calibration procedure it will fix the false battery level. More details on this article (link)

Note the device will automatically switch ON as soon as you plug it in the USB port, but that doesn't mean it is being charged: to charge the battery you need to switch the battery power to ON. There are more details on this FAQ article (link), including battery handling and care information.
