BROADR-REACH MEASUREMENT PREPARATION

Before beginning any test or data acquisition, the oscilloscope should be warmed for at least 20 minutes.

Calibration is automatic under software control and no manual calibration is required.

This procedure will be run again if the temperature of the oscilloscope changes by more than a few
degrees.

Required Test Modes

The QPHY-BroadR-Reach script requires the operator to place the DUT (Device Under Test) in the
required test modes. The script will prompt the user to do so before each specific test but it is
recommended that the operator ensures the DUT is capable of being placed in the required test modes
before beginning testing.

Physical Setup

If the operator is using the TF-ENET-B the following steps shall be completed for proper setup:

1. If the oscilloscope has BNC inputs, BNC/SMA adapters will need to be connected to Channels 2

and 3.

2. Place the TF-ENET-B board in front of or next to the oscilloscope. Ensure that it is close enough

that the SMA cables will reach.

3. Connect the 2 SMA cables on one end to the CH4 section of the TF board. They will connect to

the J33 and J54 outputs.

4. Connect the other end of each cable to Channel 2 and 3. The positive end should be connected

to Channel 2 and the negative end should be connected to Channel 3.

5. Connect the RJ45 end of the UTP/RJ45 adapter (an example of such adapter is shown below) to

the J64 input on the Channel 4 section of the TF board.
