Abstract: A signal acquisition system has a signal acquisition probe having probe tip circuitry coupled to a resistive center conductor signal cable. The resistive center conductor signal cable of the signal acquisition probe is coupled to a compensation system in a signal processing instrument via an input node and input circuitry in the signal processing instrument. The signal acquisition probe and the signal processing instrument have mismatched time constants at the input node with the compensation system providing pole-zero pairs for maintaining flatness over the signal acquisition system frequency bandwidth.
Abstract translation: 信号采集系统具有信号采集探针，其具有耦合到电阻中心导体信号电缆的探针尖端电路。 信号采集探头的电阻中心导体信号电缆通过输入节点和信号处理仪器中的输入电路耦合到信号处理仪器中的补偿系统。 信号采集探头和信号处理仪器在输入节点处具有不匹配的时间常数，补偿系统提供极零对，以保持信号采集系统频率带宽的平坦度。
