Design Notes
Unified RFB RFI and Time Domain Analysis
This example illustrates how the PORT_SRC and PORT blocks allow VSS to simultaneously perform RFB/RFI and time-domain measurements on the same system diagram.
...
In the "RF Link" system diagram we are sweeping the order of the image rejection filter and observe its effect on the noise figure of the RF link as well as the gain at the image frequency, which in this case is at an offset of 400 MHz above the carrier.
