Siglent SSM5124A, 9 kHz–9 GHz RF Switch Matrix, 2‑Input to 24‑Output

The Siglent SSM5124A is a 50 Ω RF switch matrix designed to expand test port capacity in network analyzers, spectrum analyzers, signal generators, and other instrumentation. Featuring 2 front-end input ports (labeled A–D) and 24 selectable output ports, the unit supports USB, LAN, and TTL direct control interfaces, and includes a built-in 2.4-inch color display and navigation knob for easy local configuration. It operates over a frequency band from 9 kHz to 9 GHz, making it well-suited for multiport testing of antennas, RF modules, 5G components, and automated production or lab setups.
