Looking for a VNA that can do EMI pre-test.
Since my circuit can have up to 1GHz clock, FCC15B requires up to 5x fundamental, so I need to test to at least 5GHz.
Lower end must be below 1MHz for conductive noise. This rules most candidates out since most high performance USB VNAs are based on AD9361.
Also, I don't have an anechoic chamber, so I need to calibrate my makeshift chamber made out of a microwave oven.
Thus the need of an VNA, rather than a simple SA.
Since I also don't have calibrated antennas, I also need true 2-port capability (S11, S12, S21, S22).
And finally, since I'm constantly on the move, I need a portable one (USB or PXI).
If you have a good candidate that's for sale, please let me know.
My topt pick: Keysight M9371A. But I'm open to other options.
