OMNISCANNER

A.11 OMNIScanner Test Functions

• Wire Map

• NEXT (Near-End Crosstalk)

• Return Loss

• Attenuation

• ELFEXT (Equal Level FEXT)

• ACR (Attenuation to Crosstalk Ratio)

• Bandwidth

• Length/Delay

• Resistance

• Power Sum, NEXT, ACR, and ELFEXT

• Coax Tests: Length, Delay, Impedance, Resistance

A.12 OMNIFiber Test Functions

• Multi-mode fiber: Length, Propagation Delay, Loss

• Single-mode fiber: Loss

A.13 Transmission Performance Measurement Method

All cabling transmission performance measurements (NEXT, RL, Attenuation, and

ELFEXT) are implemented using swept frequency domain, vector, digital signal

processing measurement methods to ensure accurate, repeatable results.

A.14 Transmission Performance Measurement Parameters

The accuracy of the RF transmission performance measurements is calculated in

accordance with error models documented in related TIA documents.

OMNIScanner is designed to exceed Level III accuracy requirements. The

following table provides typical specifications for important instrument parameters

relating to the measurement accuracy models.
