One of my cable set connector to 8753ES is magnetical,
which means the SmCo can attach to it, since the
connectors are made of copper, should be non-magnetical,
is it means my connector is of problem? It seems
the copper material fo rthi s connector is not very
pure, how it effects my testing result. I use it
to test isolator built with stainless steel housings.
Many thanks for your response.

The base metal for your connector is very likely
steel or some alloy, not pure copper. So it might
have some magnetic properties. If it hase a nickel
plating, then that will also contribute to the magnetic
tendency. It should not affect your testing, even
on a circulator/isolator as long as it is in a connectorized
housing.
The main problem with magnetized
connectors is a tendency to accumulate metallic
particles in the interface that can cause poor VSWR
and in the case of high power measurements, PIM
(passive intermods) issues.
If you are worried
about magnetic connectors, find some non-magnetic
in-series connector savers to use between your test
cables and the DUT.
