BSWM-4X32CSR Image

The BSWM-4X32CSR from Becker Nachrichtentechnik is a 4x32 Switch Matrix that operates from 100 kHz to 8 GHz. This bi-directional RF switch matrix is ideal for multi-signal routings. All 4 non-reflective instrument ports can be routed to 32 DUT ports. In the case of non-routing, the ports are matched to 50 ohms. It has 4 ports for measurement instruments. This switch matrix can be used for product validation tests for DUTs (Device Under Test) with multiple antenna ports, like automotive or MIMO modules.

Each of the 32 channels is equipped with wear-free, solid-state DC power switches. This allows the insertion of stimulation voltages (14V/18V) and tones (22 kHz) to control the DUT switching state and also the simulation of LNB (Low Noise Blocks) loads. Via the integrated volt and ampere meters, the (14V/18V) control voltage and the current flow can be measured simultaneously in all 32 channels. It includes an overload protection circuit that prevents damage to the module from excessive current loads.

The BSWM-4X32CSR provides an RF-to-RF isolation of up to 100 dB, an instrument port isolation of 100 dB, and a load-to-RF isolation of 50 dB. It allows all 4 non-reflective instrument ports to be routed to 32 DUT ports. In the case of non-routing, the ports are matched to 50 ohms of impedance. Due to its good isolation properties, this switch matrix allows time efficient testing of versatile signals in level and frequency on multiple channels simultaneously without influencing each other. It includes a LAN interface for remote control and a trigger input for synchronous switching applications. This switch matrix is available in a 19-inch, 2U rackmount enclosure with SMA-female connectors.

This switch matrix is ideal for MIMO testing, RF multimedia component testing, end-of-line testing, product validation, and RF signal routing applications. Due to its high bandwidth, it can route signals of almost all current broadcast and communication standards, such as AM, FM, DAB3, GSM900, GSM1800, UMTS, LTE 4G, LTE 5G FR1, IEEE 802.11a/b/g/n/ac/ax (Wi-Fi 6E), 802.11be (Wi-Fi 7), and WiMAX 802.16.

It requires an AC supply from 90 to 260 V and consumes 10 W of power.
