I cannot believe I cannot find a solution!
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.
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 ).
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.
advise. Your help will be greatly appreciated.
