Pickering Interfaces 65-110 LXI Wideband Modular Matrix

Pickering Interfaces is expanding its range of LXI switching solutions with the introduction of the 65-110 LXI Wideband Modular Matrix.

The 65-110 is a modular platform providing a solution for connecting up to 16 of 104 X connections simultaneously to16 measuring devices on the Y axis with a usable BW of 500 MHz. A version supporting 8 Y connections is also available for use in systems requiring fewer measuring devices.

The 65-110 is fully scalable - users can add X connections in blocks of 8 from 8 to 104 connections by simply adding or removing plug-in boards to the chassis. Plug-in modules can be added by users in the field; the chassis detects the presence of the plug-in modules and configures the matrix as a single matrix. The modular construction is made invisible to the user to simplify programming and the Java-based soft front panel presents the user with a simple integrated interface reflecting the build of the matrix via the web interface.

The matrix has been designed for high BW and low crosstalk, achieving a usable BW of up to 500 MHz and crosstalk to better than 60 dB at 30 MHz and typically better than 45 dB at 500 MHz even on adjacent paths. The high performance of the matrix ensures that the 65-110 is particularly well suited to fast data acquisition systems where a limited number of measuring devices need to capture data from many potential test points; the matrix allows these signals to be connected with minimal loss and low risk of interference from other paths.

All connections are carried on SMB coaxial connectors to preserve the signal BW and ensure cabling can be adequately screened. The 65-110 includes a self-test capability that allows it to check all connection paths with the signal connections in place but not injecting current. This feature allows the matrix to be tested without having to first disconnect up to 120 RF connections. The self-test facility can be initiated through the 65-110 web pages; it requires no application program running on an external controller.

The 65-110 is fully compliant with the LXI Version 1.4 standard.
