Qxdm Software !!LINK!! aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.

Qxdm Software

Diagnostic software includes real-time data collection tools for analyzing handset and over-the-air 3G system performance, such as the Qualcomm eXtensible Diagnostic Monitor (QxDM Professional). This proven diagnostic tool for the evaluation of handsets and network performance is among a comprehensive suite of diagnostic software tools from Qualcomm that enable quicker time-to-market for new devices, streamlining of network deployments, and optimization of networks for maximized performance.

Regarding (2), yes you can use a software application such as Qualcomm QXDM to examine the signaling between the device and the network. There is a great deal of information with respect to DRX that can be captured with this software.

In a single-processor Modem (with only a baseband processor) it is rather simple: Some software on the baseband processor implements the DIAG protocol, and responds to any related requests received on the DIAG port.

Later, this became a virtual serial port over USB. Initially, this transport was a dedicated serial port/UART. The general idea is that there is some physical transport medium between the chipset/modem and an external PC, and the PC can request certain diagnostic information to be sent via that physical transport. It is not publicly documented, but there are tools from Qualcomm (QPST, QXDM) as well as proprietary third-party tools and some Free Softare projects that implement parts of it. Qualcomm Diag is the qualcomm diagnostics interface built into many Qualcomm based chipsets (or rather their software) for a long time (more than a decade). 041b061a72
