Patent ID: 8564308

Claim:
A signal acquisition system comprising: a signal acquisition probe having probe tip circuitry coupled to a resistive center conductor signal cable with the probe tip circuitry comprising at least a first resistive element and a capacitive element, the resistive element and capacitive element in combination having a time constant; and a signal processing instrument having an input node coupled to the resistive center conductor signal cable of the signal acquisition probe with the probe tip circuitry time constant mismatched with a time constant across the input node of the signal acquisition instrument; and the resistive center conductor signal cable substantially terminated in its resistive and capacitive characteristic impedance across the input node of the signal acquisition instrument; and the input node coupled to a compensation system via input circuitry disposed in the signal processing instrument, with the compensation system having an input amplifier with feedback loop circuitry comprising at least one pole-zero pair; and shunt pole-zero pair circuitry coupled to the input circuitry; wherein the at least one feedback loop circuitry pole-zero pair and the shunt pole-zero pair maintain flatness over the signal acquisition system frequency bandwidth.
