First of all, thank you for using snpview.

We checked 2 s4p files in same folder (you shared).

A. dB chart question

1. USB_HOST_TEST_SPARAMS.s4p
-It shows same chart as Lecroy viwer.

2. USB_DEVICE_TEST_SPARAMS.s4p
- It has different [S] matrix data.
- The different chart should be shown in this case.



B. Eye chart question
-Calculation server occurs data transfer problem.
- We're going to fix this problem by this week. :^)

Thanks!
Huwin.
