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.
