Abstract
A single cable, single point stimulus and response probing system allows the measurement of both low impedance stimulus measurements and high impedance response measurements using a single probe cable. Circuitry located within the probe cable receives stimulus input from the stimulus circuitry located within a test and measurement device, and delivers input to response measurement circuitry also located within the test and measurement device. Certain embodiments of the probing system use feedback supplied to an amplifier located within the stimulus circuitry to improve the accuracy of the measurement device and control output impedance. Feedback can be locally supplied from the output of the stimulus circuitry, or can be generated using an additional amplifier located within the response measurement circuitry.
