Abstract :
The programming of a small digital computer (8k store) is described for use in conjunction with a network analyser. The object was to remove automatically from swept-frequency measurements of microwave admittance the effects of loss and reflexion due to transitions between the network analyser and the device or circuit under test, as well as various intrinsic errors arising within the analyser. The work is divided into two phases, the first of which pertains to loss-less junctions only and ignores intrinsic errors in the amplitude of reflexion coefficient. In the second phase, which introduces a number of refinements, the scattering parameters of an equivalent error network are evaluated and by using these a more complete system of error correction is achieved.
