BER Test panel

The “Bit Error Rate” (BER) Test panel may be used to automate the evaluation of the bit

error rate.

8.1

Typical setup

The following diagram shows the typical environment to perform the BER Test.

Figure 24. BER Test setup

The BER may be checked in different conditions. Increasing or decreasing the level of

transmission attenuation and the level of injected noise results in a different BER value at

the receiver side. The nature of the interfering noise (AWGN, colored, single carrier, etc.)

may also impact the BER performance.

Test description

To be able to perform the BER Test, two G3-PLC platforms need be connected to the G3-

PLC GUI. Both boards need to be configured in the PHY operational mode as described in

Section 5 on page 17. The user needs to configure one G3-PLC platform in the TX mode

and the other one in the RX mode.

The user can then follow the steps described in Section 10.3 on page 43 in order to correctly

configure the nodes.

Once the nodes configuration is done, the user can open the Test panel, as explained in

Figure 25:



Click on the Plugin Settings icon in the menu bar (1)



Enable the TESTLAB panel (2)



The TESTLAB panel will appear at the right side of the tool.
