Gary,
Forgot to mention another, less mentioned, failure mode -
INTERMITTENT CONNECTION
That's where the connection fails completely OPEN and then
repairs itself. Static measurements rarely catch this one.
But, data transmission will see it.
Or, like for me, burglar alarm indications saw
Be sure to include 'unfriendly' atmosphere.
We found that most push button switches go south here from
the slightly corrosive atmosphere, more so from any wear
they ever see. You have no idear how many useless
instruments are around here now.

You don't say but it sounds as if the connector involved is rf. If rf
performance is what you are after, what you really want is a TDR to look at
the discontinuity the connection provides over time, or more accurately as a
function of the number of mate/demate cycles.

I am trying to look at measuring connector/connector resistance through a
lifetime of insertion/removal cycles – far more than what the connector
specification addresses.
Anybody have a suggestion for the test gear. I would prefer to run it at
signaling speed, but think I’m going to have to just

Charles,
If I understand your question correctly:
Look at 15.31 paragraphs b), h) and i)
a) 3) References ANSI C63.4 for the test procedure which specifies
testing with all applicable components/accessories
h) indicates that composites are tested as a system
i) indicates that accessories will

Hello,
I have a question on the system testing requirements for devices
that are Verified under the FCC authorization rules and marketed
as a system.
Can someone point me to the relevant FCC rules? I have looked and looked
and cannot seem to find it.

Hello,
I'm slightly confused with (apparently dated) reference to EN
standards which corresponds to undated reference to IEC standards.
In Annex ZA (list of normative references) of EN standards, years are
sometimes written for EN standards which corresponds to undated IEC
standards, with a
