Fiber Receiver | Agilent Technologies E1439 guide

Using the Agilent E1439

Fiber Optic Interface

If flow control is on and the fiber receiver is capable of generating flow control signals, Generate fiber mode transmits filtered ADC data after the fiber receiver indicates that it is ready and a complete data block is ready to be transmitted. ADC data is not available via any other data port and received optical data, other than the flow control signals, is ignored. The following illustration shows an E1439D transmitting data to a fiber receiver when flow control is on.
