I have been using agilent NFA 8975A for gain and noise figure measurements. Recently my NFA is giving the noise reading all wrong that is it is reading 2-3dB more than the actual noise reading. I have also calibrated the NFA a number of times but it has no effect on the noise reading. Kindly let me know as to what the problem could be with my NFA and how it can be fixed?
