5.4.11.2. Measurement and Data Analysis
1. Connect DUT (Figure 5-4).
2. Press Trace Next
3. Press Start > and set start frequency to 1 MHz.
4. Press Stop > and set stop frequency to 5.1 GHz.
5. Press Trigger > Single.
6. Confirm the measured far-end crosstalk is lower than the limit shown in Table 5-9.
7. Press Trace Next
8. Confirm the measured far-end crosstalk is lower than the limit shown in Table 5-9.
Table 5-9 Far-End Crosstalk Limit between MHL and CBUS or VBUS
Frequency
>30 M to 300 MHz
>300 M to 5.1 GHz
(*) Excursions are permitted to -11.5 dB for the frequency range of 825 to 5100 MHz if
the differential insertion loss of the cable meets the below:

Frequency (MHz)
9. Repeat the same measurements for all the connections in Table 5-8. When measuring
crosstalk between CBUS and VBUS lanes, confirm the measured crosstalk is lower
