PS ACR-F
PS ACR-F results show how much the far end of each wire pair is
affected by the combined far-end crosstalk from the other pairs.
PS ACR-F is the difference (in dB) between the test signal and the
crosstalk from the other pairs received at the far end of the
cabling. The tester uses the ACR-F values to calculate PS ACR-F.
PS ACR-F results are typically a few dB lower than worst-case
ACR-F results. Higher PS ACR-F values correspond to better
cabling performance. Figure 43 shows the PS ACR-F plot. The
tester puts the cursor at the worst margin.
Note
If the PS ACR-F result is an , the 67 dB rule
applies. See “About dB Rules” on page 90.
