Product description

With the continuous improvement and needs of market testing capabilities, Getuo Microwave will develop DC-67GHz high-performance & high-precision test cable assemblies, which are equipped with compression-resistant, torsion-resistant, waterproof, Super soft and multi-color matching and other multi-functional protective armor. The diameter of the armor can be controlled within 4.8mm. Through the fine assembly process of cable components, the mechanical phase and bending stability are not affected by the protective armor. Thus it is applied to major laboratory measurement, darkroom measurement and network analyzer test line.
