產(chǎn)品簡介
理想可變增益放大器的帶寬與增益設(shè)置無關(guān),增益設(shè)置對于測量快速信號(hào)和脈沖非常重要。FEMTO的DLPVA放大器的帶寬保持恒定在100KHZ(-3 dB),直到高增益設(shè)置。通過將上截止頻率切換到1KHZ,可以降低寬帶噪聲。
六種不同的DLPVA型號(hào)提供了高度的靈活性。我們的客戶可以選擇單端或真差分輸入。雙性型號(hào)的輸入阻抗為1mω或更低,場效應(yīng)晶體管型號(hào)的輸入阻抗為1tω,可以測量非常高阻抗源的信號(hào)。后,DLPVA-100-BUN-S型號(hào)的噪聲低至0.4 nV/√Hz。

Six different DLPVA models offer a high degree of flexibility. Our customers can choose either a single ended or a true differential input. The input impedance is 1 MΩ or lower for our bipolar models and an exceptional high 1 TΩ for our FET models allowing measurements of signals from very high impedance sources. Finally the noise is as low as 0.4 nV/√Hz for the model DLPVA-100-BUN-S.
