I have general question regarding 4-port s-parameter files. Does anyone
know if there is a generally accepted industry standard for node
numbering?
I have seen both of these schemes used in various places:
a)
+-----+
1---| |-----2
| |
3---| |-----4
+-----+
b)
+-----+
1---| |-----3
| |
2---| |-----4
+-----+
It has been my observation that scheme a) is the most common and
intuitive (when I think S12 I think transmission and when I think S13 I
think crosstalk) however scheme b) has popped up often enough to be a
possible contender.
Comments???
