Abstract
A description of the program software written for the computer is given and methods are presented to enable both the sweep speed and vertical deflection factor settings of the sampling oscilloscope to be calibrated to a precision of greater than 0.5%. Details are provided of refinements made to the extrapolation method of time-referencing the data. The necessity of using a reference waveform and the advantage of using one particular configuration of the air lines in the coaxial line system are then discussed. Experimental details are given and it is shown that experiments yielding 50 frequency points can be performed typically in less than 17 min.
