OMNISCANNER User Guide
A - 6
· Measurement Accuracy: Significantly exceeds Level III requirements
· Measurement resolution: 0.1dB
ELFEXT (Equal Level FEXT)
· Tests from both directions using OMNIREMOTE and reports all 24 pair
combinations.
· Frequency Range: 1 to 300 MHz
· Dynamic Range: >100dB
· Measurement Accuracy: Significantly exceeds Level III requirements
· Measurement Resolution: 0.1dB
ACR (Attenuation to Crosstalk Ratio)
· Computed for 6 pair combinations from both ends at all frequency
points from the respective pair to pair NEXT and Attenuation mea-
surements.
Bandwidth
· Computed for the link or channel under test, bandwidth indicates the
highest frequency for which the worst case pair to pair crosstalk
(NEXT) is at least 3dB less than the attenuation.
Length
· Range: 0 to maximum distance, where max. distance
= 457 m (1500 ft.) for twisted pair cable
· Accuracy: ± K ± Length resolution ± NVP uncertainly,
where K = ± 4% of length or 0.6 m (2ft.), whichever is greater.
· Length resolution: 0.3 m (1ft.)
Resistance
· Range: 0 - 500 Ω
· Accuracy: ± 0.5 Ω @ 0 to 15 W, ± 2% @ 15 to 500 Ω
· Resolution: 0.1 Ω
Power Sum NEXT, ACR and ELFEXT
· Computed for 4 pairs from both ends from the respective pair to pair
NEXT, Attenuation and FEXT measurements.
Optical Measurements (OMNIFIBER)
· +3dBm to -55dBm
· .01dB resulution
· ± .25dB typical accuracy
