cable signature
A six-character alphanumeric code that changes with any change in interconnections.
Valid characters include the numbers 0 through 9, and the letters A through F.
connection resistance Option setting that allows you to select the maximum allowable resistance that a
“good” connection can have.
connector adapter
Connector adapters are adapters mounted on small printed circuit boards, that allow
you to connect the cables you want to test to the 1000HN. There are three types
(single-high, double-high, quad-high). Each adapter has its own unique adapter signa-
ture. Adapters are usually kept organized in a 3 x 5-inch card file. You identify the
adapter by its signature, either on the cardboard sleeve in which the adapter is
shipped, or by the signature printed on the label on the adapter itself. Adapters are
identified by the connector they mate to, not the connector mounted on the adapter.
connector adapter
position
The location either on the analyzer’s main unit, or on an expansion box where con-
nector adapters are mounted. The main unit has four such positions, marked as J1, J2,
J3, J4. Each expansion box also has four connector adapter positions.
control
The regulation of manufacturing or assembly processes; particularly the use of a cable
signature for verifying the test setup against the documentation.
cable documentation The written definition of how a cable should be constructed. Usually consists of a
wirelist, and a complete set of notes on what connectors, materials, and special
techniques should be used to build the cable successfully.
hipot
Hipot stands for
HI
gh
POT
ential. Hipot tests are done to verify that the resistance
between pins that are not supposed to be connected is sufficiently high. Generally
used to check the effectiveness of insulation and/or spacing between conductors in a
cable.
hipot duration The length of time for which hipot voltage is applied to each net during hipot testing.
Insulation Resistance
Option setting that allows you to select the minimum allowable resistance between
points that should not be connected.
insulation short An insulation short occurs when the resistance of a connection is higher than the
Connection Resistance setting, and lower than the Insulation Resistance setting. In
other words, the connection has a resistance too high for the analyzer to see it as a
“good” connection, and too low for the analyzer to see it as effective insulation.
interconnection
A situation where continuity exists between two connector pins. Continuity most
commonly exists here because a wire connects the two pins.
