The setup is two 30cm cables connected by a through for each VNA. 4 Port VNA1_Original and VNA2_6_Layer Comparison.PNG

Works great so far and one can select either VNA to verify that everything is on track and then switch to the Dual VNA or the name you create. Note: If the Dual VNA mode does not populate all the graphs just switch to either VNA and then back to Dual VNA. Also, note the limitation in mixed mode as to no phase between the two units.
