摘要：
A low capacitance signal acquisition system has a signal acquisition probe having a low capacitance input circuit coupled to a compensation amplifier in a signal processing instrument via a signal cable. The low capacitance input circuit, the signal cable and the signal processing instrument input have mismatched time constants with the compensation amplifier having feedback loop circuitry providing adjustable gain and pole-zero pairs for maintaining flatness over the low capacitance signal acquisition system frequency bandwidth.
