Transferring data

You can transfer data from the Agilent E1439C or D via the VMEbus. With the Agilent E1439D you can also transfer data via the Local Bus and via a fiber optic interface.

•The VMEbus is the universal data bus for VXI architecture. It provides flexibility and versatility in transferring data. Transfers over the VMEbus are 16 bits or 32 bits wide.

•The Local Bus on the Agilent E1439D supports faster transfer rates than the VMEbus. For example, if you are transferring data from the Agilent E1439D to the Agilent E9821, the Local Bus provides a direct pipeline to the Agilent E9821’s DSPs.

Using the Local Bus, you can transfer data in the background while processing data in a signal-processing module. All Local Bus data transfers originate in the Agilent E1439D and move towards a signal processing module to the right of the Agilent E1439D. If other modules generate data to the left of the input module, the Agilent E1439D passes the data to its right and inserts or appends its own data at the beginning or end of the frame.

•The fiber optic interface, available on the Agilent E1439D, provides data rates greater than 200 Mbytes/second. It can transmit filtered or unfiltered data, copy data from its receiver to its transmitter, or append data to copied data.
