Two key oscilloscope calibration functions test dynamic response (rise time) and bandwidth. They are also the most challenging. The goal is to faithfully transmit the calibration wave forms to the input of the oscilloscope under test. Over the years various transmission methods have been developed to overcome VSWR and other error sources. Some are more practical and cost effective than others. This paper summarizes a series of experiments that compare the traditional and more complex method of using pulse and leveling heads to simpler and more practical coaxial cables to perform these calibrations.
