A disadvantage of the cascade configuration is that the signal may pass through more than one switch contact to the device under test, causing higher losses in the signal.
级联配置的一个缺点是信号要经过多个开关触点才能到达被测装置，会造成信号的损耗更高。

The results of field test showed that adopting cascade geophone pattern can be results of good continuation of phase, enhanced amplitude and high signal-to-noise ratio on the records.
实际野外试验结果表明，采用串联检波器串的方式所得记录的相位连续性好、振幅增强，信噪比较高。
