Measurements
The FrameScope 350 makes the following test measurements. See
“Setting the Measurements” on page 129 for more details.
Wiremap
Wiremap testing checks for proper continuity and termination of cables.
The test identifies the following faults:
• Short circuit
• Open circuit
• Reversed pairs
• Transposed pairs
• Split pairs
• Shield continuity faults
Length
Length measurements determine the electrical length of cable runs up to
1100 feet (335 meters). Accurate length measurements require accurate
NVP settings. Choosing a cable type from the FrameScope’s database
automatically loads NVP settings, or the NVP for a cable can be
measured on a sample (
“Learning the NVP of a Cable” on page 138).

Propagation Delay and Skew
The Propagation Delay test measures the one-way propagation delay
over each pair of the tested cable run. Skew is the difference in
propagation delay between the pairs with the longest and shortest delay
in a cable.
