Picoammeter amplifiergain can be changed as in the voltmeter circuit by using the combination shown in Figure 1-11.
和电压表电路一样，可以使用如图1 - 11所示的组合电路来改变皮安表放大器的增益。

The experiment results show that phase phenomena are probably caused while the servo amplifiergain and the amplitude of input signal increase to some extent.
实验结果表明，当伺服放大器增益和输入信号的幅值较大时都有可能促成系统的相位突变。

Simulations have been done through adjusting parameters such as input signal amplitude, feedback gain, amplifiergain, comparator gain and the position of the phase compensator.
