At this stage the software asks the user to select only one spacer with the full frequency span activated. This expedient has to be used only to perform this measurement the right way: a single spacer with a full frequency range in the actual environmental conditions is the conditions in which the calibration has to be done. After this step the user can go back to their desired configuration of the spacers and frequency ranges. | ||
