Using the Agilent E1439
Fiber Optic Interface
Fiber Optic Interface
The E1439D provides a fiber optic interface that can transmit continuous full bandwidth data
from the internal A/D converter. In addition, it can stream data from multiple synchronized
modules operating at lower bandwidths onto a single fiber optic channel. An optical receiver can
then simultaneously analyze data collected at different frequencies and bandwidths.
The E1439D fiber optic interface uses a serial data stream protocol providing high data
throughput and low latency characteristics. This protocol is intended to be compatible with the
Serial Front Panel Data Port Draft Standard (VITA 17.1, draft 0.5 dated February 26, 2001)
currently under development by the VITA Standards Organization (http://www.vita.com). VITA
17.1 is not yet approved and manufacturers are not yet permitted to claim conformance to the
draft standard. However, laboratory testing at Agilent Technologies has demonstrated
interoperability of the E1439D with fiber optic products from other manufacturers that also intend
to support the draft standard. These products include Systran Simplex Link Protocol products,
such as the SL100 and SL240, and Mercury Computer products, such as the RINOJ-F RACEway
I/O daughter card.
The following overview supplies the basic concepts required to use all the supported features. For
details, see the descriptions of the API functions.
