I have PXA connected to the power amplifier output through coupler and attenuator. So between Power amplifier output and PXA input, there is a frequency dependent loss. I am entering this loss as .csv file to the PXA and when correction is turned on, all of the measured trace data is adjusted as per the loss in the correction table. But for some reason, the reference level is not getting changed as per the correction table data. For R&S instruments, there an option to turn on this and the reference will be adjusted automatically as per the data in the correction table. How to handle this in PXA?
