Allion Electrical Multiport System (AEMS)

AEMS is a fully upgraded automated signal integrity measurement system specifically designed for PCIe and USB4/TBT.

This solution accelerates PCIe and USB4/TBT testing, reduces the test cycle duration, and enhances both the productivity and utilization rate of measurement equipment.

Challenges in Signal Quality Testing

As AI and high-speed computing evolve, the demand for high-speed data transmission continues to rise. This surge in demand introduces significant challenges to maintaining signal integrity, underscoring the importance of PCIe electrical signal measurements.

PCIe Signal Quality Measurement

Extensive Measurement Effort:
Tx testing of an 8-slot (x16) server based on PCIe 5.0 involves up to 4,608 eye patterns and takes 40–41 days to complete.

Compromised Test Scope:
Industry challenges have led to a 50-80% reduction in full test coverage, significantly compromising quality assurance.

Quality Assurance Impact:
Manual testing processes increase the risks of errors.

AI/Automation Demand:
A non-compromising solution is needed to optimize both efficiency and accuracy.
