Hi SI gurus,
While using VNA to measurement traces on PCB for loss and Dk/Df
extraction, my colleagues say the differential handhold probe head can
have wider bandwidth than single ended handhold probe head. Is it true?
Can someone help to explain the reasons?
Also, for Dk/Df extraction, which is better structure, using single ended
or differential traces? Why?
Thank you for helps in advance.
Thanks,
John Lin
