Additional product details

The VT Series VNA Test Cables are the result of advanced engineering to meet the stringent requirements of vector network analysis up to 67 GHz. They provide a stable connection with minimal insertion loss and excellent return loss.

The cable assembly is reinforced with a stainless steel armor that prevents crushing and over-bending, significantly extending the lifespan of the cable in busy lab or production environments.

The VT Series cable also has a long flex life for production use.

Key Capabilities & Applications

Repeatable measurements under flexure

Phase stability ranges from ≤1.5° to ≤3°, depending on connector configuration, measured with a 10 cm diameter mandrel. The full table separates phase and amplitude limits by configuration.

Protected precision interconnects

Ruggedized stainless-steel armor and triple shielding provide a durable cable assembly with −100 dB shielding efficiency.

Configuration matched to the VNA

Choose N-type, 3.5 mm, 2.92 mm, 2.4 mm or 1.85 mm connectors for 18, 26.5, 40, 50 or 67 GHz coverage. Standard length is 63 cm; custom lengths are available on request.
