86 Chapter 3
Measurement Synchronization with LXI-B
IEEE 1588
Synchronizing Time on the MXA and MXG
Verifying Time Synchronization on the MXA and MXG
To verify that both instruments are running PTP, open Interactive LXI
from a PC which is connected to the same switch as the MXA and MXG.
This program is bundled with the Agilent IO Libraries Suite.
Task Action Notes
1. Connect the MXA and
MXG to the LAN
Plug Ethernet cables from each
instrument into the same
switch.
The switch should have a
connection to a DHCP
server.
2. Power on the MXA and
MXG
3. Set the MXA’s PTP
Domain
:LXI:CLOCk:PTP:DOMain 0 The parameter may be
any integer between
0-255
4. Set the MXG’s PTP
Domain
:LXI:CLOCk:PTP:DOMain 0 Make sure this domain
number matches the one
entered in Task 3.
Task Action Notes
1. Open Interactive LXI Start, All Programs, Agilent IO
Libraries Suite, Utilities,
Interactive LXI
This operation should be
performed on a PC
connected to the same
subnet as the MXA and
MXG.
2. Open the Timing menu Click on the tab labeled “Timing”
3. Choose an active domain. Select the domain entered as the
Active Domain in the pull-down
list.
This should be the same
as entered in step 3 of the
procedure “Synchronizing
Time on the MXA and
MXG” on page 86.
4. Update the clocks Click Update Clock List
5. Check that the MXA and
MXG are located in the
expected domain.
Click on the Clock Names listed
in the Clock List, then examine
the Clock Information panel for
the IP Addresses of the MXA
and MXG
6. View the PTP LAN traffic. Click the PTP Messages tab and
select the Timing Messages
checkbox.
