On June 12, 2026, a team of professional engineers from Beijing Doewe Technology Co., Ltd. rushed to a radio and television transmitting station in Hainan to carry out special professional training for the RWC2500A Plus Broadcast Modulation Analyzer. The training helps technical staff of the station consolidate equipment operation capabilities and strengthen the technical guarantee foundation for safe FM radio broadcasting.
The training was closely tailored to the on-site operation and maintenance demands of the transmitting station, and implemented in strict accordance with the industry standard Technical Requirements and Measurement Methods for Metric Wave FM Radio Transmitters (GY/T 169-2001). Firstly, it elaborated on FM signal modulation principles, stereo FM framework and basic knowledge of various carrier signals, and disassembled test specifications for core indicators including transmitter distortion, signal-to-noise ratio and channel separation. Secondly, it explained in detail interface parameters, product strengths and standardized test procedures of the RWC2500A Plus broadcast modulation analyzer. Featuring integrated design, high measurement accuracy, portability, easy operation and automatic test report generation, the equipment meets the localized operation and maintenance demands of the station. In addition, the training supplemented the working principle, parameter debugging and fault troubleshooting skills of the spectrum analyzer. Combined with on-site practical drills, engineers guided staff members to independently complete full-index detection and daily operation calibration of FM transmitters in accordance with industry specifications.

The participating technical staff studied earnestly throughout the training, and raised practical questions combined with daily operation and maintenance work. The engineers gave detailed answers to each question one by one, and arranged on-machine practical exercises simultaneously, ensuring all participants proficiently grasp key points of instrument operation.
This special training has effectively improved the professional testing competency of relevant staff and strengthened the quality control capability of broadcast signals. In the future, Doewe Technology will continue to provide on-site technical empowerment services for radio and television transmitting stations nationwide. With comprehensive after-sales technical support, the company helps national wireless radio stations realize high-quality, stable and safe broadcasting.
