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.
