On the MXG ATE, if you are unable to establish a LAN connection, cycle power on the MXG ATE, press the LAN Reset hardkey.
This resets the MXG ATE to a factory preset where the Web-Enabled MXG ATE feature is available (i.e. Web Server softkey is set
to On).
For MXG ATEs, press the front panel LAN Preset key and wait for the front panel green LAN indicator light to stop blinking. It is
possible the hostname may have been changed from its default value. The MXG ATE hostname is not changed by pressing the
LAN Reset key. For information on using the MXG's USB port to query its IP address, refer to the Agilent Connectivity Guide
(E2094-90009) or to the LAN Connectivity FAQs for details on using the instrument over LAN.
For more information on LAN Connectivity, refer to the Agilent Connectivity Guide (E2094-90009), or the signal generator’s
Programming Guide, or to the LAN Connectivity FAQs for details on using the instrument over LAN.

Self Tests Do Not Run or Self Tests Run Slowly
If self tests will not run or run slowly, the most likely cause is a faulty A1 Power Supply or A5 CPU assembly. The A5 CPU assembly relies
on correct power supply voltages. If the A1 Power Supply is faulty, it could cause a false A5 CPU assembly error.
1.
Troubleshoot the A1 Power Supply. Refer to
“A1 Power Supply” on page 1-26
2.
If troubleshooting the A1 Power Supply does not correct the problem, troubleshoot the A5 CPU assembly. Refer to
3.
If self tests still will not run or run slowly, the fault can be identified within the boot-up routine. Use the following
procedure to identify and isolate the problem.
