4. Press ENTER. Press ESC to abort the test. (Press the arrow keys to select
another cable test standard.)
NOTE
When the AUTO TONER is ON, the toner function is activated whenever a
remote is not attached and the main unit is set to Quick Check or
Autotest. When a remote is attached, the toner is turned OFF
automatically and the test proceeds. This makes it easy to identify which
cable is ready to be tested next.
6.11 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.
