VNA Seriese: Test Cable for Vector Network Analyzer (1000mm)
VNA Seriese: Test Cable for Vector Network Analyzer (1000mm) provides stable and accurate RF signal transmission for microwave measurement systems. Designed for vector network analyzer testing, RF calibration, antenna measurements and microwave laboratories, this high-performance phase stable coaxial cable ensures reliable measurement accuracy and repeatable test results.
VNA Series: Precision Armored VNA Test Cables (1000mm Length)
AO Microwave’s metrology-grade 1000mm VNA test cables are designed to deliver exceptional phase and amplitude stability under continuous movement across wide frequency ranges up to 50 GHz [3.3.4]. Built with low-density expanded PTFE (ePTFE) dielectrics and gold-plated copper contacts, these test cables are protected by a heavy-duty, multi-layer stainless steel armor sleeve. Operating up to 50 GHz [3.3.4] with metrology-grade connector interfaces (NMD and standard 2.92mm/2.4mm), our 1-meter VNA assemblies achieve a low input VSWR, low insertion loss, and outstanding phase stability of typically < 5° at 40 GHz under standard bending.
These high-performance armored assemblies are engineered to provide extra physical reach in spacious laboratory environments. The 1000mm length is optimized for routing signals to large devices under test (DUT) or environmental testing chambers, maintaining stable calibration.
Managing Mechanical Load & Phase Stability in Longer Test Leads
Longer VNA test cables (like 1000mm) provide wider physical reach but present unique challenges. A 1-meter armored cable is heavier, which can apply significant downward mechanical load on the VNA's front panel bulkheads.
Additionally, the longer physical path increases phase sensitivity to movement. AO Microwave’s 1000mm armored VNA cables are designed with ultra-low-density expanded PTFE (ePTFE) dielectrics and heavy-duty, multi-layer stainless steel armor to distribute bending forces. This construction maintains tight concentricity, keeping phase drift below < 5° at 40 GHz while utilizing robust NMD connectors to protect the VNA bulkheads.
Target Applications & Operational Advantages
By providing low insertion loss and high phase stability under flexure, our 1-meter VNA test cables secure critical measurement paths:
Spacious VNA Test-Bench Setups
Function: Connects large devices under test (DUT) or multi-port test systems directly to VNA ports.
Advantage: Extended 1000mm length provides the necessary physical reach while maintaining calibration-grade phase and amplitude stability under movement.
Environmental Chamber Testing
Function: Routes high-frequency test signals from external VNAs into thermal/vacuum test chambers.
Advantage: Exceptional mechanical durability and wide temperature stability allow the cable to withstand harsh environmental chamber cycles.
Anechoic Chamber Antenna Scanning
Function: Connects moving measurement probes to stationary VNA ports inside anechoic chambers.
Advantage: Low phase drift under continuous movement prevents systematic scanning errors, ensuring accurate far-field transformations.
