Hi, I am trying to obtain frequency-swept Gain and Group Delay plots through a frequency converter modeled in VSS. I have set up a VNA block with the FSTART, FSTOP, FSTEP specified as input (stimulus) signal frequencies, but am having trouble setting up the "S21_PS" & "GD_TD" measurements such that the frequency conversion is taken into account. I have the Frequency sweep variable set to "Use for x-axis" but am not seeing anything on the graph, and am confused as how to specify the output (response) frequency in general.
