A Method to Solve the Probe Load Effection in the High Speed Digital Circuit

Free registration required

Executive Summary

The measuring result has much business with the performance of the oscilloscope probe. First the authors analyze the probe load effection, and then present a method to solve the problem by using the probe attenuator. After that in order to identify the accuracy of the theory, they do a careful detailed consequence process. Finally they bring up the factual circuit of the whole method. During measuring, it is often considered that the voltage in circuit remains steady with or without oscilloscope. However, every probe has its import resistance that includes electrical resistance, capacitance and inductance heft.
