- Overview
The SYSTEM conducts field testing of communication transmitters operating within the frequency range of 100 MHz to 600 MHz in order to evaluate the technical performance parameters of radio equipment under actual deployment and operating conditions. The system performs continuous transmission power testing and real-time monitoring to ensure stable and compliant operation. In the event of abnormal deviations, performance degradation, or transmitter faults, the system will automatically issue alerts, record corresponding errors, and store detailed fault information for subsequent analysis.
The SYSTEM measures and evaluates key signal parameters of radio communication equipment, including transmission frequency range, output signal strength, and received signal levels from external radio terminals. The measurement results are used to assess the influence of terrain characteristics, environmental conditions, and surrounding interference sources on radio propagation capability, as well as to compare actual field performance against standard reference conditions defined for ideal environments.
The Main Control Module manages the parameter configuration process for each measuring device, corresponding to specific measurement procedures and target test objects. The collected data is then analyzed and evaluated by the system to support technical condition assessment and enable rapid and accurate fault detection (if any).
The system supports the measurement and analysis of high-frequency RF signals across the 0.1 to 1 GHz frequency range, with a maximum continuous-wave (CW) input power of 50 W.
Additionally, the SYSTEM supports spectrum analysis with high frequency resolution and dynamic range to detect interference sources and signal anomalies more effectively. It also integrates GPS-based positioning for precise geolocation of measurement points, enabling accurate mapping of signal coverage and facilitating detailed analysis of radio propagation performance across different terrains.
