、矩形波、斜坡波及自定義波形生成，為複雜測試場景提供了完備的信號模擬能力。

核心應用場景：從理論到實踐的跨越

太陽能係統測試成為這一技術的典型應用領域。通過內置函數發生器模擬太陽能電池板的I-V特性曲線，工程師能夠精確測試太陽能逆變器的最大功率點跟蹤能力。基於EN 50530標biao準zhun的de測ce試shi模mo式shi，係xi統tong可ke以yi模mo擬ni輻fu照zhao度du變bian化hua和he溫wen度du波bo動dong對dui太tai陽yang能neng電dian池chi輸shu出chu的de影ying響xiang，為wei兆zhao瓦wa級ji太tai陽yang能neng農nong場chang的de逆ni變bian器qi測ce試shi提ti供gong完wan整zheng解jie決jue方fang案an。
