appcad version 3.0.2
Please note: There are two "undocumented features" (as Microsoft refers to bugs) in this prototype version 3.0.0 of AppCAD:
1. All "DB" formatted S2P files will incorrectly return the error message "S2P file contains S12 = 0". The workaround for this issue is to reformat the S- parameter file into magnitude-angle "MA".
2. S-parameter files with frequency units of "Hz" will be incorrectly displayed by a factor of 10. (All other frequency units are correct.) A simple workaround is to adjust the analysis frequency. For example, to sweep a desired frequency range of 1000 to 3000 MHz, set the frequency range to 100 to 300 MHz.
They apologize for this inconvenience. An updated version of AppCAD that corrects these two issues will be available very soon.
Let us wait updated version!
best regards.
