Why Location of Port Reference Affects Crosstalk

為什麼端口參考的位置會影響串擾？
串擾是信號完整性的關鍵指標。 然而，端口參考的不同位置可能引起不同的串擾量。 它不僅發生在模擬中，也發生在測量中。 每個信號完整性工程師都必須意識到這個問題。
Crosstalk is key metric in signal integrity. However, different location of port reference could induce different crosstalk amount. It happens not only in simulation but also in measurement. Every signal integrity engineer must get aware of this issue.

Thanks so much for the videos! every problem I've had with my simulations has been resolved by watching one of your videos!

Very well explained, thank you!

Both port setups are wrong. Should have set it up as waveport catching the "screw" in the corner as well as the GND strip in the middls.

Thanks so much, but which one is the true situation in ciuruit?
