The GSOLT implementation in VNATools appears to require the thru port pairs 1/2, 1/3, and 1/4, in that order. Is this correct?
This is a problem for wafer probes with fixed pitch where there often isn't a "cross" standard. For example, we have ports 1 and 3 assigned to our device's inputs and ports 2 and 4 assigned to our device's outputs. We have thrus 1/2, 3/4, 1/3, and 2/4.
