供應(yīng)HP35665A 動態(tài)信號分析儀 / 音頻頻譜分析儀 / 音頻掃頻儀

生產(chǎn)廠家: 惠普/安捷倫

具有內(nèi)置信號源的通用FFT分析儀，適用于常見的頻譜和網(wǎng)絡(luò)分析，以及倍頻程、階次與關(guān)聯(lián)分析。內(nèi)置信號源具有可選的分析特性，可以優(yōu)化分析儀的性能，以便對噪聲、振動和聲學(xué)問題進行分析和故障診斷，評測并解決旋轉(zhuǎn)機械問題，以及表征控制系統(tǒng)參數(shù)。

多種測試方法

快速傅立葉變換、擺動正弦測試、聲頻分析、次序分析、相關(guān)分析、頻率直方圖/時間測試等，并具有測試結(jié)果加工功能，能使機器對信號的處理達到一定的高度及深度。

測量結(jié)果：時間記錄、線性譜、功率譜、功率密度、頻率響應(yīng)、相關(guān)、自動/互相關(guān)、正態(tài)分布、PDF，CDF。
顯示類型：單圖、雙圖、兩條曲線同圖顯示、狀態(tài)及水流圖顯示。
更新速度：8條曲線/秒
