Coax Cable Connections
In most cases, coax cable is connected directly to the TDR or through a
connection adapter. In some case via a test lead. If the test lead and adapters
are all well matched, this generally results in a smooth transition from the TDR to
the cable under test. See figures 3-6 and 3-7.
