Hello,
I need some tips to measure harmonics from a transmitter (~1W) with a spectrum analyzer. I know that I need to use notch or high pass filter to remove the fundamental freq and so avoid the AS input from saturating. My concern is in this case the impedance seen by the transmitter at fundamental. I can use an attenuator to hide the mismatch at fund freq but this would be harmfull for the dynamic range. A circulator is also a solution but I don't have wideband enough.
Do you have any suggestion or test set-up for this measurement?
Thanks a lot.
