Length and Propagation Delay
The length measurement shows the length of the center
conductor in the cabling.
Differences between measured and actual lengths can be caused
by variations in the cable’s NVP value. NVP values can vary among
cable types, lots, and manufacturers. In most cases, these
differences are minor and may be ignored.
Propagation delay is the time taken for a test pulse to get to the
end of the cable. The delay is measured in nanoseconds. One
nanosecond is one-billionth of a second, or 0.000000001 second.
Figure 79 shows the results from a length test.
