Wire Map
· Finds miswires, opens, shorts, crossed and split pairs and presents
results in a schematic format
· Includes shield test if connected
· Uses OMNIREMOTE for complete mapping of wiring at both ends of the
cable
NEXT
· Test all six pair combinations from both directions using OMNIREMOTE
· Frequency Range: 1 to 300 MHz
· Dynamic Range: >100dB
· Measurement Accuracy: Calculated per TIA error model
· Accuracy: Significantly exceeds Level III requirements
· Measurement Resolution: 0.1dB
Return Loss
· Measures Return Loss on all four pairs from both directions using
OMNIREMOTE
· Frequency Range: 1.0 to 300 MHz
· Dynamic Range: > -35 dB
· Factory Calibrated to ensure measurement port match to reference
100 ohm impedance.
· Measurement accuracy: Significantly exceeds Level III requirements
· Measurement resolution: 0.1dB
Attenuation
· Tests all four pairs using OMNIREMOTE as far end active signal injector.
· Frequency Range: 1.0 to 300 MHz
· Dynamic Range: > 60 dB
