DUT: Device-Under-Test, the wire, cable, or harness being tested by the cable tester. (Sometimes called UUT or Unit-Under-Test.)
Fixturing: The wires and connectors that connect the DUT to the tester.
Hipot: Cirris uses the term “hipot” synonymously with “high voltage” when speaking about high voltage (hipot) testing or high voltage (hipot) testers. For more on this definition, see our Hipot vs. High Voltage blog post.
Learn: Cirris testers create new test programs by building a list of instructions based on a cable attached to the tester. This process is called performing a Learn.
Test Program: The set of information defining the tests to be performed on a DUT. This includes information on the DUT’s connectors, connections between connector pins (test instructions), test parameters, etc.
