用于核磁测量仪的测量系统
摘要：
本发明涉及一种用于核磁测量仪的测量系统，其带有控制器、信号发生器以及信号处理器，信号处理器带有输入级和信号调节器，信号调节器用于处理由激励信号引起且在输入级的输入部处进入的电测量信号，其中，同样由激励信号引起并且未与测量信号同时出现的干扰信号在输入级的输入部处进入，测量信号的信号摆幅小于干扰信号的信号摆幅，控制器确定激励信号的输出的时刻。匹配可由信号处理器处理的最大信号摆幅与由激励信号引起的测量信号的最大信号摆幅的测量系统由此实现：在输入级的输出部与信号调节器的输入部之间布置有开关，开关可由控制器切换到第一切换状态和第二切换状态中，并且信号调节器的输入部的动态范围与测量信号的电压摆幅相匹配。
摘要（英）：

The system (1) has a signal generator (3) for generating electric excitation signals, and a signal processor (4) for processing measurement signals. A switch (7) is arranged between an output of an input stage (5) and an input of a signal conditioner (6). A controller (2) switches the switch to a state in which a signal at the output of the input stage is passed to the input of the signal conditioner, and another state in which the signal is not passed to the input of the signal conditioner. Dynamic range of the input of the conditioner is adapted to voltage deviation of measurement signals.
