Precision VNA Cables for Accurate S-Parameter Measurements
VNA Test Cables Engineered for Measurement Accuracy
Gore VNA Microwave/RF Test Assemblies are optimized for vector network analyzer measurements, providing the stable phase response and low insertion loss your calibration and device characterization work demands across the full measurement frequency range.
Precision VNA test cables optimized for vector network analyzer measurements, providing stable phase and low insertion loss across the full measurement frequency range. Designed to minimize cable-induced measurement error in S-parameter, impedance, and gain characterization setups.
Why Choose Gore VNA Microwave/RF Test Assemblies?
Minimized Measurement Uncertainty
VNA accuracy depends directly on the stability of the cables connected to its ports. Gore VNA assemblies maintain consistent phase and amplitude characteristics even when the cable is repositioned between measurements, keeping your calibration valid and reducing the measurement uncertainty budget contributed by cable variability.
Low VSWR for Clean Reflection Measurements
S11 and S22 measurements are exquisitely sensitive to connector and cable VSWR. Gore's precision-manufactured connectors and controlled dielectric geometry minimize mismatch reflections throughout the measurement chain, allowing the true device reflection to dominate rather than cable artifacts.
Optimized for Daily Lab Use
VNA port cables are connected and disconnected dozens of times daily in active labs. Gore VNA assemblies are built for this duty cycle — with robust connector interfaces rated for thousands of connection cycles and flex-resistant cable construction that maintains electrical performance through continuous repositioning.

Frequently Asked Questions
Are Gore VNA assemblies compatible with all major VNA brands?
Yes. Gore VNA assemblies use industry-standard connector interfaces (SMA, 2.92 mm, 2.4 mm) that mate directly with port connectors on Keysight, Rohde & Schwarz, Anritsu, Copper Mountain, and all other major VNA platforms.
How often should VNA test cables be replaced or recalibrated?
There is no fixed replacement interval — cable condition should be monitored by performing a cable verification check (e.g., comparing S11 ripple against a known standard). Gore VNA cables maintain their specifications for significantly longer than economy alternatives due to superior construction, reducing recalibration frequency.
What is the difference between VNA assemblies and PHASEFLEX® assemblies?
PHASEFLEX® assemblies target the highest-performance applications with best-in-class phase stability specifications and are rated for millions of flex cycles. Gore VNA assemblies offer excellent performance for standard VNA measurement work at a more accessible price point, making them well-suited for general laboratory use.
Can RSTECH provide torque wrenches and handling accessories with the cables?
