VPX 3U High Speed Signal Integrity Test Card Kit

Introduction

To support the increasing market demand for higher bandwidth in OpenVPX/SOSA systems driven by high-resolution multi-spectral sensor fusion, real-time edge-AI inference, and cognitive electronic warfare—Comtel introduces its next generation of VPX 3U High Speed Signal Integrity Test Card.

Based on COMTEL’s Air-/-Plane 56TM technology these 3U VPX cards are designed validate the latest high speed Ethernet protocols defined in the IEEE Std 802.3cd (50GBASE-KR, 100GBASE-KR2, and 200GBASE-KR4).

The cards design is optimised with a small differential impedance mismatch from the cable SMA interface to the Multi Gig RT3 connector (<10%). The characteristics such as insertion loss, return loss, crosstalk, etc. can be measured with an external Vector Network Analyzer (VNA) with 4 ports or similar equipment (capability up to 40 GHz is recommended)

Product Features

  • Perfectly suited to validate VPX/OpenVPX/SOSA backplane performance in a VPX system as well as standalone.
  • Excellent signal integrity beyond 28 GHz, to support up to 56Gps (PAM-4) validation per pair.
  • 3U VPX form factor, fits in both conduction and convection cooled slots
  • All 68 VPX high speed links available for characterization
  • High density compress mount interface to bring high speed links out of the card to external measurement equipment
  • Test card including high speed cable adapter fits into a single 0.8″ slot of a VPX backplane
  • Integrated loopback link to allow for de-embedding

Benefits

  • No need to extract a backplane out of a system to perform links characterization
  • Mechanical kit allows for converting between conduction and convection cooled style mechanics
  • Every single high speed link on a backplane can be characterized
  • Complete S-parameter set as well as crosstalk can be captured with 3 test cards and 4 cable adapters
  • Insertion and Return loss are minimized to enable accurate characterization of backplane high speed links
  • Integrated loopback link connection to measure and de-embed the measurement test assemblies from the final SI report
