Phase-stable flexible microwave cable assembly
CABxx high-stability low-loss cable assemblies are the type of cable we recommend running the distance in a good OTA setup. Having cables that are amplitude and phase stable along the path from the positioner to the instrument and from the instrument to the probe/horn post contributes to trusted measurement results.

When it comes to wiring an OTA antenna test setup equipped with a 3D positioner there are 2 separate wiring issues to address.
The first issue is to use a phase-stable and flexible cable to get out of the moving sections of the positioner. The second issue is to get the lowest loss cable to run the distance between the probe and the DUT especially when using a VNA setup.
For the first equation a great quality low profile cable assembly is what we are looking for with CLPxx products.
For the second lowest loss stable cable assemblies like CABxx are most desired.
