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.
