A400DI

带相位逆变器的双通道高电压放大器

带相位逆变器的双通道高电压放大器

概述

Pendulum Instruments双通道高压线性放大器 A400DI 包含两个独立的 A400 放大器,它们共享公共接地参考和电源。它还具有一个低压相位逆变器,可对通道1的输入信号进行反相,然后,生成的信号可以通过短 BNC 电缆(随附)连接到通道 2 的输入端,因此通道1和通道2的输出信号反相,此时在通道1和通道2的输出之间连接负载可以有效地使电压幅度加倍。请注意在这种工作模式下负载不能有任何接地。此外,为了查看负载两端的电压信号,您必须使用两个示波器探头测量并使用数学运算得到结果。

具有相位逆变器的放大器型号有 A400DI 和 A800DI,测试连接如下图所示:
