Section 10: Rework and Guided Assembly / Testing Awkward Assemblies
1000M User’s Guide / page 42
Testing Extremely Short Cables
If a cable is so short that it will not reach between two cable adapters installed on the
analyzer, create extension cables that span the necessary length at each end, to allow
the cable you want to test to be connected.
Testing short IDC-type cables
If you need to test short IDC-type cables, it may be convenient for you to build a
daisy chain of assemblies. You create a series of short cables, each followed by a
short length of ribbon cable that connects it to the next cable. Test the assembly as a
daisy chain, then cut away the excess ribbon cable between the assemblies.
Testing cables with many connections
Cables with lots of connections are easy to test if they consist of a daisy chain of iden-
tical connectors with identical interconnections.
Just plug each identical connector into the analyzer in succession to test them. How-
ever, if the interconnections are not identical, you must check each feasible combina-
tion of connectors. This will mean you’ll have to test and document several different
connector combinations.
Testing harnesses and backplanes
The 1000M easily tests harnesses with less than 128 termination points. Do these
things:
1.
Select connector adapters which have a large enough number of pins for you to
create an interface cable that will connect from the analyzer to each termination
point on the harness board.
2.
Label the termination points with equivalent pin numbers.
3.
Document and test the assembly as though the harness were a cable assembly.
