I'm currently performing bandwidth analysis on multiple systems, and would like to know if there is a way to increase the precision of the results (bandwidth, peak, Q factor, and loss) to match that of the marker precision used to take the data. When queried from the machine and output to a csv file , the results are carried out to 7 digits, but when looking at the trace data for the analysis I see the marker values are carried out far beyond this to 11 or 12 digits. Seeing as how the bandwidth, peak, and also Q factor are all functions of only the markers frequency position, shouldn't these measurements be as precise as the marker location itself?
In other words, is there any way to have the leading digits from the results of a bandwidth analysis match that of the marker? Or is this not possible due to how the PNA itself performs the task?
