特點
?多功能,高精度,高速度,可遙控音頻分析儀
?此儀器綜合了低頻信號發(fā)生器、電子電壓表、失真表、頻率計、直流電壓表的功能于一身。中央微處理器控制意味著可靠性更高,操作更簡便,將眾多的功能匯集在一個小型、高速、高精度的單元中,其價格比分立單元更具有競爭性。
?使用DSP技術(shù),通過FFT計算獲得真RMS值
?使用DDS技術(shù)的高速、高穩(wěn)定度信號發(fā)生器
?寬大的LCD提供了清晰精確的顯示
?配備GPIB接口
?為通訊應(yīng)用提供了SINAD測量
?雙通道輸入/輸出可進行通道互擾、分離及L/R率測量
?頻率計及AC電平頻率范圍擴展至210KHz
?具THD的失真及諧波分析功能
?操作簡便,測試功能豐富
