10Base-T Peak Differential Output Voltage on TD Circuit
4. Locate the 5 MHz signal after a stable trigger is obtained and measure positive and negative
peak voltages. See Figure 17-2. Locate regions of three periods for each signal to ensure the
peak voltage is not affected by transitioning from a 5 MHz signal to a 10 MHz signal or from a
10 MHz signal to a 5 MHz signal.

5. Record the values.
6. From the 10 BASE-T PHY Configuration Tests menu in gigconf.exe, select the Amplitude
10MHz: 1411.10.02 test.
7. Repeat step 3.
8. Locate the 10MHz signals after a stable trigger is obtained and measure positive and negative
peak voltages. See Figure 17-3. Locate regions of three periods for each signal to ensure the
peak voltage is not affected by transitioning from a 5 MHz signal to a 10 MHz signal or from a
10 MHz signal to a 5 MHz signal.
9. Record the values.
10. Verify the measurements meet specifications.
