VNA Uncertainty Calculator Limitation

Is the KeysightUncert.xls Rev.2.6.1 limited to calculating only S parameter uncertainties of linear DUTs?  We are trying to determine if it can be used to determine S parameter uncertainties of a mixer as the DUT when you have a 1.5 GHz RF signal out of an N5242A Test Port1, a 1.35GHz LO signal out of Source 2 Out2 and a 150MHz IF signal into Test Port2.  If the spreadsheet can't be used, could you point me to something in the literature that would deal with this case?
