Choosing the right cable factories is hard and often times it's hard to obtain, let alone understand complicated test reports. The GRL DI Tester from Granite River Labs makes it easy to quick test cables and big data techniques are applied to make it easy to analyze and compare cable quality using a benchmark scoring system.
Good quality cables have 1) less overall loss through the cable, 2) linear loss profiles, 3) ample margin to specification requirements, and 4) production consistency. The better the quality the cable, the more insurance you have to prevent unwanted connection issues. Click here to learn more about the cable testing and scoring methodology.
