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。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(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爭性。
·使用DSP技術(shù)，通過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jq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(jìn)行通道互擾、分離及L/R率測量
·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
·操作簡便，測試功能豐富
