Automatic Selection of Connecting Cables for In-line Test

An apparatus includes an interface to a device-under-test (DUT), an interface to a rack of cable holders, and a control circuit. Each cable holder is configured to raise or lower respective cable. The control circuit is configured to determine an internal configuration of the DUT and, based upon an internal configuration of the DUT, identify a plurality of cables to be used in testing the DUT. The control circuit is configured to cause the rack of cable holders to actuate a plurality of the cable holders associated with the identified plurality of cables to raise or lower the cable holders associated with the identified plurality of cables.
