Using the Agilent E1439

Fiber Optic Interface

Copy

The Copy fiber mode copies optical data from its fiber receiver to its fiber transmitter without adding any data. Normal data collection and filtering continues, and the data port selection determines whether data is sent to the local bus (Agilent E1439D only) or read from the FIFO via the VME bus. Copy is the default fiber mode after power-on or reset. See the following illustration.
