ACR and Power Sum ACR Test
The ACR (Attenuation-to-Crosstalk Ratio) test performs a mathematical
comparison (difference calculation) between the results of the Attenuation and
NEXT tests. The difference reading between each pair gives an indication of how
problem-free the cable pair will be for transmissions.
The ACR measurements are calculated pair-to-pair.
Note: The RH is required to perform these tests.
