Signal Switching Units Ssus

Programmable Signal Switching Units (SSUs) for Advanced Telecom Testing

Signal Switching Units (SSUs) from Orbis Systems are advanced programmable platforms designed to simplify and automate RF signal routing. These systems play a vital role in telecom and wireless testing by managing the flow of signals between test instruments and Devices Under Test (DUTs). Instead of manually reconnecting RF cables, SSUs provide a reliable, repeatable, and automated method for executing complex test sequences, reducing setup time, minimizing human error, and improving test repeatability.

Flexible and Scalable Design

Orbis Systems’ SSUs are built with a modular and scalable architecture, allowing them to expand alongside evolving test requirements without a complete redesign.

They are suitable for a wide range of environments, from R&D labs and validation setups to production testing, and can be configured for different matrix sizes, port counts, and frequency ranges.

Wide Frequency Coverage

The SSUs support a broad frequency range from DC up to millimeter-wave bands, making them ideal for legacy telecom, 5G, and beyond-5G applications.

Their ability to maintain high accuracy and low loss across wide bandwidths ensures dependable performance for telecom, aerospace, defence, and automotive industries.

High Performance for Complex Testing

The SSUs deliver low insertion loss, high isolation, and excellent repeatability, ensuring consistent RF performance.

They are available in multiple configurations, including blocking and non-blocking matrices, variable attenuator matrices, and phase-shifter matrices, enabling flexible integration into complex test architectures.

Easy Control and Integration

Equipped with programmable control software and automation-ready interfaces (e.g., LAN, GPIB, USB, or RS-232), Orbis SSUs are easy to configure, monitor, and maintain.
They support real-time diagnostics and integrate seamlessly with Over-the-Air (OTA) chambers, positioners, and other automated test equipment, forming a complete test solution for 5G and OTA validation systems.

Why Choose Orbis SSUs

By automating RF signal routing, Orbis Systems’ SSUs enhance test repeatability, reduce downtime, and increase overall throughput. They help organizations accelerate product validation cycles while maintaining the accuracy and reliability required in modern RF testing.
