Items used for diagnostics
1) Voltmeter to check 12V on the backplane (optional).
2) External diagnostic brackets with F-F connectors if needed.
3) Diagnostic GUI available on MultiLane’s public website. The file is here.
Quick checks before running hardware diagnostics
Ping Check
Start by trying to ping an instrument using its IP address to make sure that the instrument is
turned ON and a proper Ethernet connection is available.
Docking Checks
See Advantest manuals for proper docking procedures.
Is AT93000 Twinning Frame properly docking to V93000?
Is DUT Loadboard properly docking to AT93000? This can be done manually or using
the Advantest docking remote control.
Twinning Frame Cables Routing Checks
Checking the cable routing do not get pinched by the bridge beam (every service engineer
should have a 3D printed bridge beam to check this). A pinched cable can be the field problem,
so these kinds of things should be checked before touching the instruments.
Is the +12V power cable in good condition?
Are the Ethernets cables in good condition?
Both air cables are in good condition?

Diagnostic GUI
When the GUI is opened, three options are available: “Load from Model File”, “Skip”, and “Create a
Model File”.
1. Load from Model File: allows the user to browse a previously made Model File containing
the instruments info including IP addresses in order to run diagnostics with a simple click.
One can always manually add additional instruments.
2. Skip: allows the user to only manually add the instruments needed for diagnostics.
3. Create a Model File: user can use this option to create or modify a model file in a simple
and
easy
way.
Refer
to
Appendix
I
for
more
info.
Figure 7: ATE Diagnostic GUI
Once the instruments are inserted, by loading a model file or adding them manually by specifying
the IP and type as shown in Figure 8, the user can begin the diagnostics process.
Figure 8: Adding Module
AT-BERT
Connect to your desired BERT by clicking on the red dot next to it; the dot should turn into
green in case of successful connectivity. Once a connection is secured, the user will be able to
access three different sections listed below. “Save” button will allow user to save all the
instrument’s info shown in Module Settings and Loopback sections, while the bottom Logger
section lists the successful processes.
10

Module Settings
In module settings the user will be able to detect the instrument’s temperature in addition to
the board revision, FW revision, calibration, IP address, supported FW options, and others, as
shown in Figure 9.
Figure 9: Module Settings
Monitor
In the monitor section, the user can track the different settings applied to the BERT including
the amplitude, pre- and post- emphasis, 7 taps, Tx and Rx pattern, and others, as shown in
Figure 10.
Figure 10: Monitor

Loopback
In loopback section, the user first must “initialize” in order to generate a signal from the BERT.
The GUI will specify what settings are being set, and it can be also tracked in the Monitor
section. After initialization, a refresh button should be clicked to get latest BER and SNR
values. One should also check the lock bar highlighted below, if the lock goes green next to a
tested channel, then the BERT transmit and receive sides work well.
Figure 11: Loopback
AT-DSO
Connect to your desired DSO by clicking on the red dot next to it; the dot should turn into
green in case of successful connectivity. Once a connection is secured, the user will be able
to access two important different sections listed below. “Save” button will allow user to save
all the instrument’s info shown in Module Settings and lock status of Monitor section, while
the bottom Logger section lists the successful processes.
12

Module Settings
In module settings the user will be able to detect the instrument’s temperature in addition to
the board revision, FW revision, FPGA revision, IP address, supported FW options, calibration
coefficients (by clicking “Load Calibration”), and others, as shown in Figure 12.
Figure 12: Module Settings
Monitor
In the monitor section, the user will be able to detect Eye diagrams of the signal coming from
the BERT (if connected). First click on “Configure” and select the specs of the signal received
from the BERT as shown in Figure 12. Then click on refresh to detect the eye diagrams, Figure
13. One should also check the lock bar highlighted below, if the lock goes green next to a
tested channel, then the DSO receiver and clock input are working well.

Figure 14: Monitor - Eye Diagrams
AT-BERT and AT-DSO
The user can connect to as many BERTs and DSOs as needed using the Diagnostic GUI. By that,
one should refer to the Loopback section of the BERT to generate a signal and detect it on the
Monitor section of the DSO.
Change IP address, Firmware and FPGA
If the IP address, Firmware and FPGA needs to be changed, the field service engineer needs
to be referred to our public website, V93000 ATE Test Solutions and refer to the Application
Notes where you can find the PDF about Changing IP, FW, and FPGA.
The user could change the IP address and Firmware through the Diagnostic GUI using a USB
cable over an Ethernet cable.
Using AT1000 backplane: The user should plug the USB cable into the connector
located on the backplane.
Using AT4000 Backplane RevD: The user should plug the USB cable into the connector
located on the backplane and plug the instrument into the U453 Slot of the backplane.
The user could change the FPGA through the Diagnostic GUI using an Ethernet cable.
Using AT1000 backplane: The user should use an ethernet cable.
Using AT4000 Backplane RevD: The user should use an ethernet cable and can plug
the instrument into any slot of the backplane. (U450, U451, U452, U453)
Refer to Appendix II for more info.

Appendix I: Create a Model File
This option allows the user to create or modify a model file by clicking on “Load” or “Save”, in
addition to the “add” and “remove” buttons concerned in instruments.
1. Add: as seen in Figure 19, adding an instrument will request the type, IP, number of channels,
slot number of the cassette location and the name of the instrument that can be set to the
user’s desire and not necessarily the real name of the instrument.
Figure 18: Adding Instrument in Model File
2. Remove: after adding an instrument, or if a model file is loaded, one can always delete one of
the instruments channels or drag all of them to delete the entire instrument as shown in Figure
20.
In addition to the previous, the following can also be done as seen in Figure 20:
NOTES:
1. Add model file description
2. Specify the calibration status of the BERT: OFF, Factory, or custom by writing the path
of the calibration file extracted from the ATE Calibration GUI available on MultiLane
website.
