Return Loss

· Measures Return Loss on all four pairs from both directions using

OMNIRemote

· Frequency Range: 1.0 to 300 MHz

· Dynamic Range: 0-25dB

· Factory Calibrated to ensure measurement port match to reference

100 ohm impedance.

· Measurement accuracy: Designed to meet Level III accuracy require-

ments.

· Measurement resolution: 0.1dB

Attenuation

· Tests all four pairs using OMNI

Remote

as far end active signal injector.

· Frequency Range: 1.0 to 300 MHz

· Dynamic Range: > 80 dB

· Measurement Accuracy: Calculated per TIA error model

Accuracy: 100 MHz - 0.6 dB, 200 MHz - 0.7 dB, 300 MHz - 1.0 dB

· Measurement resolution: 0.1dB

ELFEXT (Equal Level FEXT)

· Tests from both directions using OMNI

Remote

and reports all 24 pair

combinations.

· Frequency Range: 1 to 300 MHz

· Dynamic Range: >100dB

· Measurement Accuracy: Designed to meet Level III accuracy require-

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 measure-

ments.

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.
