The invention relates to a linear dynamic calibration source system, in particular to a high-accuracy high-linearity high-temperature-stability dynamic calibration source system. According to the high-accuracy high-linearity high-temperature-stability dynamic calibration source system, automatic gain control of a power level is achieved by using of a negative feedback loop. Power output in a large dynamic range is achieved by using of an electronic stored program control attenuator. In an automatic gain control loop circuit, high accuracy degree of power is achieved by using of a synchronous real-time compensating radio frequency detector, linear compensation and temperature compensation. High-linearity output of the power is achieved in the whole dynamic range, and consistency of the power output in the whole working temperature range is ensured.

Traffic service signaling data in signaling chain of stored-program control exchange in each telecom dept. are corrected through signaling correction unit in real time. Signaling correction unit through network port transfers corrected data to signaling corrector. The signaling corrector stores traffic service signaling data onto storage. Signaling decoder in call ticket generation module decodes signaling data in the signaling corrector; and based on signaling data flow, call data record (CDR) is generated. According to time period, CDR is converted to file CDR so as to generate original call ticket data. File transferring server in the call ticket generation module saves signaling data (original call ticket data) decoded by signaling decoder in a designated directory for computer to down load. Further, voice service analysis module and assistant balance module can be added to the system in order to carry out voice service analysis and settling accounts.
