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. kew is the difference in propagation delay between the pairs with the longest and shortest delay in a cable.
