Elma accessories include:

– Test extender boards in VPX, VME64x, VME, cPCI, ATCA, VXS, MTCA, and VXI architectures, designed to extend plug-in cards outside of the card cage area for easier testing.
– Load boards for various architectures designed to aid in verifying that the chassis can meet the power requirements of the system specifications, and helps the engineer locate hot spots in the chassis.
– Power Interface Boards for pluggable power supply modules. Air blocker/filler boards that fill empty slots, jumper for bus like VME, and re-direct or contain airflow.
– Form factor extenders for various architectures such as VPX, VME64x, VME, cPCI, ATCA, VXS, MTCA, and VXI.
– Cabling solutions for VPX / OpenVPX.
– SerDes test modules directly evaluating true Gbps serial link BER performance inside the chassis.

VITA Backplanes: VPX, VXS & VME

VITA Backplanes: VPX, VXS & VME

Elma developed the industry’s first VPX backplane and proposed several profiles to the VITA 46 subcommittee. Since then, Elma has developed various VPX and OpenVPX configurations with and without legacy VME64x slots. VPX presents design challenges with higher layer-count backplanes, and more demanding power and cooling requirements. Elma tackled these problems with comprehensive signal integrity analysis and testing.

Elma offers a complete range:
– VME64x
– OpenVPX backplanes
