So I am gradually learning how to put together a reasonable ODS using mescope and a comtest vb8. So far I have managed a few passable examples. Although my ODS's seem to be a fair representation of what I expect based on previously collected phase readings the information that is extracted from the vb8 confuses me. I was expecting a single 'reading' for each measurement point (ODS FRF) but instead there is a fourier spectrum, coherence and cross spectrum for each measurement point downloaded from the vb8 into mescope. When I generate the animantion equations (automatically match points) the equations generated seem to use all the data (coherence, cross sepctrum, forier spectrum). Does this mean that the software is generating the ODS FRF out of these three parameters?
