Secondly, with the aid of developed 4TP-single-terminal-port transform device, capacitance value of single-terminal-port capacitor is measured by 4TP impedanceinstrument.
然后，借助于研制的精密四端对-单端口转换器，用四端对阻抗测量仪测量单端口电容器容量值；

Instrument speed is most often a consideration when making low impedance measurements.
在进行低阻抗测量时，常常要考虑测量的速度。

In this paper, impedance matching between LPF and surveying instrument is discussed and the design method is presented.
