          signal comprehensive analyzer

          This product is developed by our company for the uplink fault diagnosis of the terminal of the low-voltage centralized copying system. It can detect the signal strength of each standard network of the three major operators, and provide the operator and network standard with the best signal to provide judgment for the on-site personnel. in accordance with. This product integrates 3 independent signal detection channels, each channel can diagnose SIM card faults independently or simultaneously, and each channel automatically supports signal detection of the whole network and all standards (supports all standards of mobile, telecom and China Unicom detection). Each channel supports automatic detection of SIM insertion, automatic identification of SIM card information (CCID, IP, operator, network standard, etc.), automatic identification of base station location information (CELL_ID, LAC), uplink PING detection, and uplink master station login detection and other functions.
