    The reference is used for power loss and delay measurements. Setting a reference lets your DSP-4000 test tool automatically subtract out the losses or delays due to patch cords or the DSP-FTA410 units. The loss and delay for a fiber under test is automatically calculated as the difference between the reference loss and delay and those values measured with the fiber inserted.
