Pasternack has introduced a portfolio of ruggedised phase stable VNA test cables that operate up to 40GHz. The VNA test cables are geared to withstand harsh test lab use and production testing for 50 communications systems.

The phase stable cables can be ordered with male or female versions of SMA or Type-N connectors for cables operating to 18GHz, 2.92mm connectors for cables operating to 26.5GHz or 2.4mm connectors for test cables performing up to 40GHz.

Ruggedised VNA test cables

Torsion resistant connector heads are directly attached to stainless steel conduit style armouring providing a rugged design for up to 5,000 mating cycles with proper care. The cable's armouring enhances amplitude and phase stability by preventing stress due to over bending while maintaining the flexibility required for testing in a lab environment, noted the company.

The ruggedised VNA test cables have a maximum phase change of 2 at 18GHz, 3 at 26.5GHz and 5 at 40GHz with typical calibration procedures. Minimal phase change is essential because amplitude and phase variation following VNA calibration can cause inaccurate S Parameter measurements. As a result, amplitude and phase stable cables are needed to make accurate VNA measurements.
