Correcting method for level indicator of antenna measurement device - by measuring signal of known level at defined frequencies and using linear interpolation

摘要

The method of correcting a level indicator of an antenna measurement device for errors caused by the individual frequency characteristic of the measurement device involves determining the correction values for defined equidistant frequencie values in different channels by measuring and storing a signal of known level. Intermediate correction values are derived by linear interpolation. The appropriate correction value is added to the measured value with correct sign. Correction value for boundary frequency values are determined experimentally. USE/ADVANTAGE - Automatic correction by computer circuit built into antenna measurement device.
