Articulated Lines as RF Test Cables Replacement

SPINNER developed articulated lines to replace the RF test cables between the test port of a vector network analyzer (VNA) and the device under test (DUT). Other than conventional RF test cables they have an excellent phase and amplitude stability, even in motion and at very high signal frequencies.

The use of several rotary joints between rigid line  sections allows the end of the line to be easily moved to all points within a sphere of approx. 0.5 m in radius (without restrictions such as the limited bending radius of a cable).

The choice of materials ensures high reliability and a long life time of the lines.

SPINNER articulated lines are available in connector types 3.5 mm and N.
