I have a N9020A MXA which maximum frequency is 26,5 GHz. I measure the carrier power around 26GHz and it is too low, that is, I would have -40dBm and I get -70dBm. I think it should be close to the power source carrier. For that, I would like to know the frequency response about this instrument to try to explain why decrease.
Could I measured by myself? or is there any file which show me it?
