I am using N5242B ( SMC and NFx applications) to measure an up/down converter. The conversion gain and NF are showing higher value (  5dB) than a standard setup ( Sig Gen and SA). Is there any thing critical I am missing in my PNA settings? Thanks

My DUT input is at -30dbm and expected conversion gain is 20dB. The PNAx is measuring 25dB.
