A method and apparatus adapted to calibrate a test probe and oscilloscope system such that loading effects of the probe are substantially removed from the measurement. A signal under test from a device under test is coupled to the test probe and used with selectable impedance loads in the test probe to characterize transfer parameters of the device under test. A trigger signal synchronized to the signal under test is coupled to the oscilloscope system to trigger the oscilloscope. An equalization filter in either the frequency or time domain is computed from the device under test transfer parameters for reducing in signal error attributable to the measurement loading of the device under test.
