Software Operation
3.1 Preparation
Prepare the G0430A for operation according to the following steps.
1. Install the GUI software on the host PC or MP1900A.
2. Verify jumpers are present in the positions listed on Table 3.1-1.
3. Connect the device under the test (hereafter, DUT) outputs to the
MAEQ-39904B Ch1 inputs with the Carlisle connector cables.
4. Connect between the MAEQ-39904B Ch2 outputs and the MP1900A
ED inputs by using 2.92mm Carlisle connector cables.
5. Make sure the necessary hardware connections for the G0430A are
in place, and launch the User Control software by going to Start >
All Programs > MACOM Technology Solutions.
6. Make sure the software is active, click Connect.
The device will be recognized and displayed in the upper-right
corner of the window.
7. On the right side of the Channel Control tab, click Reset with No
OTP Download to reset the device.
The Channel Control tab helps you control the settings for each of
the four channels individually.
The high frequency boost can be controlled by using the slide bar or
by inputting a decimal number between 1 to 127 (in Figure 3.1-1).
Channel control also allows control over the settings like, low
frequency boost, bias control, and disabling the channel (and in
Figure 3.1-1).
On the individual channel tab , each of the four channels can be
configured differently.

3.2 How to Optimize Return Path
For Receiver LEQ Test with PCIe Gen5 (32GT/s), it is important to
optimize Return Path (DUT Tx to BERT ED). The procedure is shown
below.
Requirements for using the G0430A
When testing the System, connect the G0430A between DUT Tx and ED.
Refer to Chapter 2 “Connection Procedure” for how to set up the G0430A.
Though the G0430A is not required for AIC Test, it is the same as the
method of optimizing Return Path for System / AIC test.
Return Path optimization procedure
Follow the steps below to optimize the Return Path.
Optimization procedure
1. Refer to the Receiver Link Equalization Test section and set up the
test configuration according to the figure below.
2. Start MX183000A, set Specification to Gen5, and then turn off all
the stresses below.
●SJ
●RJ
●DMI
●CMI

3. In the MX183000A main screen, select the Setting check box for
LEQ Te st, and follow the stepｓbelow:
3a. Set PPG Starting Preset to P5.
3b. Set DUT Initial Preset (Preset Hint Tx) to P9.
3c. Set DUT Target Preset (Change Preset) to P9.
3d. Click Apply.
3e. Click Option, and then on the PPG / ED tab of the Option dialog
box, set CTLE Gain to 0.0 dB.
Figure 3.2-2 LEQ Test Setting of MX183000A Link Training
4. Turn the G0430A on, set equalization parameters in Figure 3.1-1 to
Set No.0 first, as shown in Table A-1, and then click Link Start,.
5. Click Link Start.
6. Establish Loopback.
6a. If Linkup Speed is not 32.0 Gbps and the LTSSM State is not
Loopback.Active.Lead, increase the Set No of the Table A-1 (for
example, Set No.0 -> Set No.4 -> ... -> Set No.20) by 4 steps and
re-execute Link Training. Confirm every time whether
Loopback is established through the LTSSM State displayed.
6b. If Loopback cannot be established despite EQ is set to Set
No.20, set the Preset settings in steps 3a and 3b to P8, set EQ
to Set No.0, and then check the Loopback status according to
step 6a again.

Chapter 3 Software Operation
8
6c. If Loopback cannot be established even with Preset 8, redo step
6b with P7, P6, ... P0.
6d. Check the Preset and EQ settings for which Loopback was
established in steps 6a to 6c.
6e. If Loopback cannot be established up to step 6d, remove ISI
from the measuring system and retry steps 6a to 6d.
* If Loopback cannot be established by the steps above, the
measurement environment may be incorrect (cable connection
error, etc.) or there may be a problem with the DUT, so review
the measurement environment again.
7. BER optimization
Perform Link Training with Preset and EQ settings specified in step
6 to measure BER.
7a. Optimize EQ to find the setting that gives the optimal BER.
7b. Set the EQ confirmed in step 6.
7c. Run Auto Search.
Click Operate MP1900A to switch over to MP1900A GUI.
Click the Auto Search button.
Set as below and click Start:
Mode: Fine(NRZ)
Item: Threshold & Phase
CTLE Auto Adjust: OFF
7d. Wait until Auto Search is completed, and then check BER.
7e. Increase the Set No of Table A-1 to be set in Figure 3-1 by 1 or 2
steps, and then -check the BER again. Repeat this step until the

Chapter 3 Software Operation
9
optimum BER is searched. If an error-free condition is achieved
with multiple Set Nos, use the Set No as the optimum setting.
7f. Click the Auto Search button in step 7c again.
7g. Click CDR Tune. (Optional)
8. ED setting for Return Path optimization
In the procedure up to step 7, EQ setting of the G0430A and ED
setting parameters for optimizing the Return Path are determined.
The parameters are as follows:
●Preset setting confirmed in step 6.
DUT Initial Preset (Preset Hint Tx)
DUT Target Preset (Change Preset)
●Threshold, Phase, and EQ settings confirmed in step 7.

Chapter 3 Software Operation
10.
When the settings above are applied to the following parameters for
MX183000A, optimization of Return Path is completed.
