Chapter 2: Overview
2.5 The LPV List of Functions
UTP CABLES. LAN Performance Verification Level 1 tests:
√ Length measurement of each cable pair.
√ Locates opens, shorts, and distance to the fault.
√ Locates split pairs and the distance to the split.
√ Wire map. Graphs cables’ internal pairing.
√ NEXT (near-end) and FEXT (far-end) crosstalk.
√ Propagation delay (time for data to travel the length of the
cable).
√ Skew (time delay between pairs).
√ Cable typing. CAT 3, 5, 5e, 6.
√ Speed Projection: Displays test results as a graph projecting
the cable’s speed capability (up to 1 Gbps).
UTP CABLES. LAN Performance Verification Level 2 tests. Adds:
√ Attenuation. Graphs level of real live data from PC, hub or
switch.
√ Speed Vertification (Level 2). Enhanced speed display samples
real live data on active pairs to the limit of the device (1 Gbps).
NOTE: Level 2 tests use real data from your hub, switch, or PC.
COAX CABLES:
√ Length, open, shorts, distance to fault, tone, and wire map.
NETWORK DEVICE TESTING:
√ Single-sided and inline port tests check the ability of the hub,
switch, or PC to communicate by displaying their advertised
and negotiated capabilities.
