QXDM allows authorized users to read and write to the device's Non-Volatile (NV) memory, which is essential for configuring specific modem parameters or internal settings. The Diagnostic Workflow
QXDM serves as a "window" into the internal operations of a mobile device's modem. By connecting a PC to a test device via USB or serial cable, engineers can access high-resolution diagnostic data that is typically hidden from standard user interfaces. Qxdm Software
QXDM captures and displays live statistics, events, and diagnostic messages directly from the device's Application Specific Integrated Circuits (ASICs). QXDM allows authorized users to read and write
It supports a wide range of wireless technologies, including 5G NR (NSA and SA) , LTE , WCDMA , and legacy 2G/3G standards. Engineers use it to analyze Over-the-Air (OTA) signaling messages between the User Equipment (UE) and the Base Station (gNB/eNB). QXDM captures and displays live statistics, events, and
A typical diagnostic session using QXDM follows a structured process: QxDM Professional™ QUALCOMM eXtensible Diagnostic Monitor
The tool is vital for measuring RF performance, including physical cell measurements (RSRP, RSRQ), throughput, and Block Error Rate (BLER).
