Measurement Synchronization With Lxi-B; Ieee 1588 - Agilent Technologies X Series Programmer's Manual

Measurement Synchronization
3
with LXI-B
The LXI Standard (LAN eXtensions for Instruments) brings the
connectivity of the internet to the Test and Measurement industry.
LXI-B provides a number of tools that a system integrator may use to
improve the efficiency of his measurements and improve his visibility
into his system.
This document assumes general familiarity with the LXI-C class of
instruments and aims to clarify a number of general use cases for
measurement synchronization between an MXA and an MXG using
tools provided by the LXI-B standard.
As of this product firmware release in June 2008, LXI Class B
NOTE
Compliance Tests using the new IEEE 1588-2008 Precision Time
Protocol (PTP), were not available. This product provides the features of
an LXI Class B instrument by adding LAN Triggering and Time
Synchronization to its LXI Class C compliance. References to LXI Class
B in the document and in the instrument menus and web pages do not
imply LXI Class B compliance. This product will apply for LXI Class B
Compliance when the LXI Consortium has approved its specification
changes and can provide certified testing.

IEEE 1588

The IEEE 1588 standard defines a Precision Time Protocol (PTP) for
synchronizing various clocks connected by Ethernet. This will give your
measurement instrumentation a common sense of time. To ensure that
the MXA and MXG are operating with synchronized PTP clocks, follow
the procedure outlined in the table below.
