Phase Versus Flexure Reference Data

 Astrolab performed phase tests on hundreds of minibend cable assemblies. Following are two standard Astrolab tests with the corresponding data. In test one minibend® QG-12 assembly's were flexed 90° in a 0.5 inch radius directly behind the connector. In test two, minibend® QG-12 assemblies were flexed 180° with a 1.0 inch radius in the middle. Typical data is recorded here:
