I cannot believe I cannot find a
I am trying to find a way of
calibrating small tiny semirigid coax cables (
1.2mm diameter ) for measuring S param. on RF
boards populated with 0402 components. I tried
soldering one end of this semirigid on a SMA
connector already mounted on RF board, to use it
as a reliable way of connecting my calibration
kit and use it for reflection calibration.
Then I use a semirigid coax cable ( both ends
SMA terminated ) to calibrate the trasmission,
but at the end of calibration procedure, the
measurements I took, differ a lot from "clasical
calibration" ( the one which is using just
simple coax cables ).
Where am I wrong ?
What is going on?
ADS said that is very
difficult to calibrate such stuff on 8753E
unless I am using an additional software.
Please advise. Your help will be greatly
