Switch matrices & RF switches
Expand and automate your test ports for multi-port device testing. The SSM5000A switch matrix and SSU5000A mechanical switches route RF signals across many devices — from 9 kHz to 50 GHz — without constant cable reconnection, with Siglent and other mainstream instruments.
Two ways to switch
Choose a high-density switch matrix to fan out one or more sources to many DUTs for automated production and lab testing, or compact mechanical RF switches to route individual signal paths up to 50 GHz. Both integrate cleanly into automated test systems alongside your analyzers, sources and spectrum analyzers.

Frequently asked questions
Siglent RF switch systems.
What's the difference between the SSM5000A and SSU5000A?
The SSM5000A is an automated switch matrix that fans one or more inputs out to up to 24 output ports for high-density multi-DUT testing. The SSU5000A is a set of discrete mechanical RF switches (SPDT/SP6T) for flexible signal routing up to 50 GHz.
What frequency ranges are covered?
The SSM5000A matrix covers 9 kHz to 26.5 GHz depending on model; the SSU5000A switches cover DC to 50 GHz depending on model.
How are they controlled?
The SSM5000A supports LAN, USB and direct control and is built for automated test systems. The SSU5000A is controlled over USB with the EasySSU software — both integrate easily into ATE and remote sequences.
Can I use them with non-Siglent instruments?
Yes. The switch systems work with Siglent network analyzers, signal sources and spectrum analyzers as well as other mainstream instruments, expanding the test ports of your existing setup.
How fast and durable are they?
The SSM5000A matrix switches in 10 µs. The SSU5000A mechanical switches operate in under 10 ms with a long life of up to 10 million cycles (2–5 million on the highest-frequency models).
Are calibration certificates available?
Yes. Every unit ships with a factory ISO calibration certificate, and we offer accredited ISO/DKD (DAkkS) calibration and recalibration on request — see our calibration services.
