特點(diǎn)
·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(hào)發(fā)生器、電子電壓表、失真表、頻率計(jì)、直流電壓表的功能于一身。*微處理器控制意味著可靠性更高，操作更簡(jiǎn)便，將眾多的功能匯集在一個(gè)小型、高速、高精度的單元中，其價(jià)格比分立單元更具有競(jìng)爭(zhēng)性。 
·使用DSP技術(shù)，通過(guò)FFT計(jì)算獲得真RMS值 
·使用DDS技術(shù)的高速、高穩(wěn)定度信號(hào)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(cè)量 
·雙通道輸入/輸出可進(jìn)行通道互擾、分離及L/R率測(cè)量 
·頻率計(jì)及AC電平頻率范圍擴(kuò)展至210KHz 
·具THD的失真及諧波分析功能 
·操作簡(jiǎn)便，測(cè)試功能豐富
