Delay/Delay Skew
Delay is a measure of the time electrical signals take to propagate
from one end of the cable to the other end.
The difference in propagation delays from one cable pair to
another is called Delay Skew.
The Delay test measures and displays the propagation delay of
each wire pair. The Delay Skew test measures and displays the
difference in propagation delay from each wire pair to the shortest
wire pair.
Both Delay and Delay skew are becoming important parameters
for emerging high speed LAN standards such as 100BaseT4, 622
Mbps ATM and Gigabit Ethernet.
Figure 5-2. Delay/Delay Skew
Delay and Delay Skew are tested only during an Autotest or Quick
Check. They are included in Autotest for the enhanced cable
standards (e.g. Cat5 Plus BasicLnk). These tests can be added to
Autotest or Quick Check for any other cable standard by defining a
custom cable standard - see Appendix A.
