RF Explorer Handheld Digital Spectrum Analyser - ISM Combo Plus is a powerful, high performance digital spectrum analyzer covering the 1GHz frequency range starting at 50 KHz, and 2.35 to 2.55 GHz for scanning the popular 2.4 GHz band.
It offers low frequency support from 50 KHz covering LF, MF, HF, VHF and UHF up to 960 Mhz and provides high frequency support for 2.4 GHz band starting at 2.35 GHz and covering up to 2.55 GHz.
The new SLIM design offers an outstanding robust enclosure, a more convenient USB connector on the side and larger internal battery capacity. Compared to the baseline ISM COMBO model, the new PLUS includes a higher frequency range in the sub-1 GHz band, more sensitivity and higher RF Generator power output in the 2.4 GHz band.
Most of the complexity inherent to full sized Spectrum Analyzers is simplified with automatic functionality resolved by the firmware. For instance, you do not need to adjust Resolution Bandwidth (RBW) everytime you select a different frequency span.
Actually, you do not even need to know what RBW is. You can progress in your RF learning curve and come back to this manual and online tutorial anytime.
