Recently, a team of professional technical engineers from Beijing Doewe Technology, together with its core product, the RWC2500A Plus Broadcast Modulation Analyzer, launched a national technical exchange tour for broadcasting stations. Boasting core advantages including multi-standard coverage, high-precision measurement and user-friendly operation, this instrument has become a focal point of attention in the radio and television industry.
The RWC2500A Plus fully supports multi-standard demodulation for AM/FM signals, covering the AM frequency band from 500 kHz to 30 MHz and the FM frequency band from 76 MHz to 108 MHz. A single unit can meet testing requirements across multiple scenarios, with a radio frequency (RF) measurement accuracy of ±0.5 dB.Its core breakthrough lies in its integrated audio testing capability: it comes with a built-in audio generator featuring balanced/unbalanced/digital multi-interface options, with the reference audio total harmonic distortion (THD) as low as 0.02%. When adjusting the output level, users can observe the modulation degree changes in real time. Key metrics including AM positive-negative amplitude modulation asymmetry, signal-to-noise ratio (SNR), frequency response and isolation can all be tested automatically. In the future, a one-click automation function for transmitter indicator detection will be launched, along with automatic report generation, which will significantly improve testing efficiency.Weighing only 5 kg with a compact size, and equipped with a 5-inch color touch screen, the device achieves remarkable enhancements in portability and user operation experience.
During the exchanges, the engineers conducted on-site demonstrations of the device’s applications in scenarios such as transmitter operation and maintenance, as well as signal calibration. Its flexible performance, which is suitable for both laboratory testing and outdoor field measurements, has been well recognized by radio and television technical personnel across the country.With localized technical support and rapid service response, the RWC2500A Plus transforms radio and television operation and maintenance from a time-consuming and labor-intensive process into one that is efficient and hassle-free.For more product details, please visit Doewe Technology’s official website at www.doewe.com or call 010-64327909.
