NBIoT / LTE Cat-M Signal Strength Tester

The NB IoT Tester has been designed for this purpose and it is fully skilled for testing and analysing the digital signal levels in the air Signal strength is measured in dBm The presented Digital and quality levels are RSSI, RSRP, RSRQ and SNR. The unit displays the real time values in numerical form but also in the shape of thermometer scales. These are all easily readout with low values in red and acceptable values in green. The NBIoT Tester is easy to learn and operate. It is handled with just a few buttons and the measured results are being presented on a Colour LCD.
