Siglent RF Switch Systems.

Switch matrix can easily meet the requirements of multi-port device testing, which can make the connection of multi-port device testing simple. The number of test ports of network analyzer, signal source, spectrum analyzer and other equipment is expanded. A single SSM5000A series RF switch matrix of Dingyang Technology can expand the output ports to 24, and can continue to stack. Compared with the traditional measurement method, the measurement speed is greatly improved by using RF switch matrix, which not only supports SIGLENT instruments, but also supports other mainstream instruments and meters products, which greatly adapts to the use scene of production line. SSU5000A series mechanical switches, whose working frequency range covers DC-50 GHz, can be widely used in multi-channel and multi-port test environment.

The Siglent SSM5000A Series Switch Matrix is designed to meet the growing demand for efficient, high-density, and automated RF testing. By intelligently expanding the number of available test ports, the SSM Series makes it possible to measure, calibrate, and characterize multiple devices or complex multi-port components without the need for constant reconnection of cables and instruments. This not only saves valuable time but also ensures repeatable, high-accuracy measurements in demanding test environments.

Built for versatility, the SSM5000A can be configured with up to 4 input ports and 24 output ports, covering frequencies from 9 kHz up to 26.5 GHz depending on the model. With a rugged 19-inch rack-mount chassis, intuitive 2.4-inch LCD interface, and support for LAN, USB, and Direct Control, the system integrates seamlessly into laboratory, production, or automated test setups. Its 10 μs fast switching speed and 50 Ω impedance design make it an ideal solution for high-performance RF workflows across a wide range of industries, including wireless communications, 5G, IoT, radar, and antenna testing

The Siglent SSU5000A Series Mechanical Switch is designed to meet the growing demand for flexible, reliable, and automated RF switching. By extending the number of available test ports, the SSU Series makes it possible to route, switch, and manage signals across multiple devices or test setups without the need for constant manual reconnections. This not only improves efficiency but also ensures repeatable, high-accuracy measurements in demanding RF environments.

Engineered for versatility, the SSU5000A Series includes models with SPDT (Single Pole Double Throw) and SP6T (Single Pole Six Throw) configurations, covering frequencies up to 50 GHz depending on the model. With robust SMA or 2.4 mm RF connectors, 50 Ω impedance, and low insertion loss, these switches maintain signal integrity even in high-frequency applications. Control is simple and efficient through USB interface and EasySSU software, enabling seamless integration into laboratory, production, or automated test systems.

With fast switching times down to <10 ms, long switch life (up to 10 million cycles), and compact rugged construction, the SSU5000A is an ideal solution for advanced RF workflows in industries such as wireless communications, aerospace, 5G, IoT, radar, and high-frequency component testing.
