A modular switching platform lets engineers increase matrix density, simplify servicing, and handle demanding signal-routing and crosstalk measurements.
Pickering Interfaces’ 65-217 modular 2A Ethernet-controlled LXI matrix is designed for automated test systems where switching requirements can grow after the initial system is deployed. Built for the company’s 65-200 LXI chassis platform, the module allows test engineers to increase matrix capacity without replacing the complete switching system.
The 65-217 uses front-loaded plug-in modules, with each module providing a 64×8, 1-pole matrix. Up to six modules can be installed in a single 19-inch, 2U chassis, allowing systems to scale to a 384×8 matrix. The modular approach also allows individual sections to be replaced from the front of the rack, reducing servicing effort and avoiding the need to remove the chassis from the test setup.
Software manages the path-identification offsets between modules, allowing the multiple 64×8 sections to operate as a larger matrix rather than requiring engineers to program each module independently. Versions are available with or without front-panel Y-axis access, while switched Y-axis loop-through connections allow matrix expansion between multiple chassis.
The key features are:
- 64×8 matrix architecture per plug-in module
- Up to six modules per 2U chassis
- Dual Y-axis analog bus architecture
- Front-access relay replacement provision
- Three-year warranty with long-term support
The architecture includes a dual Y-axis analog bus, enabling different external instruments to access separate portions of the matrix. It can also be configured as two independent matrices when required. Unused sections can be disconnected through switched Y-axis points to help preserve available signal bandwidth.
A key capability is support for RF crosstalk measurements on unterminated signal paths, making the matrix suitable for test applications where conventional termination is not practical. This can be relevant to aerospace and automotive test systems involving complex signal-routing and interference measurements.
For maintenance, the 65-217 incorporates relay cycle counting to help track relay usage and plan preventive servicing. Built-in BIRST (Built-In Relay Self-Test) can detect failed or worn relays, while optional external eBIRST tools provide additional diagnostic capability. Spare relays are also included on each plug-in module to simplify replacement.
The matrix supports switching of signals up to 300 VDC or 250 VAC at 2 A, with maximum ratings of 60 W or 62.5 VA. Its modular construction and long-term support make it suited to automated test systems that need to evolve alongside changing test requirements.
