Offline correction of microwave-network-analyser reflection-coefficient errors

This program has been developed to correct certain errors arising in the use of microwave-network-analyser systems. In using a network analyser to measure the reflection coefficient, errors arise from imperfections in directional couplers, source and other mismatches and crosstalk and inaccurate tracking between test and reference channels. This program facilitates calibration of the system and corrects the measurement data obtained. The use of error correction can also extend the useful frequency range of the analyser. In addition, the program can modify data for various reference planes and has facilities for graphical output on a Smith-chart display. The program was designed to run on an ICL 4100 series computer with incremental plotter, magnetic tape handlers and paper-tape station, in addition to card reader and line-printer.
