2.3 Test Equipment
• Digitizing oscilloscope with at least 1 GHz bandwidth
• Differential probe with 1 GHz or greater bandwidth
• UUTu with gigconf.exe test software
2.4 Test Fixtures
• 100 Ω UTP test load (Appendix A.1).
2.5 Test Procedure
1. Connect the test equipment as shown in the figure below.
2. Set the probe to divide by 10 and to full bandwidth.
3. Select the Amplitude and Level Accuracy: 40.6.1.2.1 Test from the 1000BASE-T PHY
Configuration Tests menu in gigconf.exe.
4. Measure the output voltage with a differential probe connected across the 100-ohm test load
for each channel.
5. Adjust oscilloscope to the settings for Point A as shown in the following table and figure:
