Abstract

A computer-based impedance measurement system coupled by means of General Purpose Instrumentation Bus (GPIB) is developed in this paper. Besides GPIB card and communication cables, the devices in the system include a computer, a slotted line, a signal generator, a standing-wave indicator and a digital multimeter. Many functions are provided by the computer in the system, such as standing-wave distribution display, automated calibration, UUT information management, certification printing, etc. The new system is more effective and stable than the currently used system in terms of positioning of standing-wave crest or trough, reading acquirement of standing-wave indicator, etc.
