I am measuring a mixer with N5242A. The LO is external Sig Gen controlled as Device0. I can measure conversion loss using segmented sweep. But I cannot get segmented sweep turned on when measuring IP3.The dual source in Port 1&2 is sweeping, e.g a fixed 1M apart over 5.8-6.3G, and the IP3 is measured. But I cannot get it to add the remaining segments to 18G as I could for conversion loss.
Can you explain the steps I need to follow??
RF IN LO IF
5.8-6.3G 10.5G 4.7-4.2G
6.3-6.8G 11.0G 4.7-4.2G
17.5-18.0 21.0G 3.5-3.0G
