NOTE
Full LXI–B feature implementation is only available on instruments with firmware >A.01.50.
A license may be required to enable this feature and to download firmware versions
>A.01.50. For information on new firmware releases, go to

This section 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 signal analyzer and a
MXG signal generator using a LAN connection. Refer to http://www.lxistandard.org/home and to
www.keysight.com/find/lxi.

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.
Time Synchronization using an MXA Signal Analyzer and a MXG Signal Generator
To ensure that the MXA and MXG are operating with synchronized PTP clocks, follow this procedure:
1. Connect the MXA and MXG to the same Ethernet switch and the ensure that both instruments
are configured for LAN operation.
2. Power on the MXA and MXG.
3. Send the following SCPI command to both the MXA and MXG:
:LXI:CLOCk:PTP:DOMain 1
This parameter may be any integer between 0 to 127. The default value is 0.
