Continuous innovation.
UFI — New hardware
10G Ethernet and GMSL2 support
New generation UFI adds support for 10G Ethernet and GMSL2 interruption testing — ready for next-generation vehicle architectures.
SignalGeneration — Software
Feedback measurements and multi-amplifier support
Software upgrade adds feedback measurements during interruption and short-circuit tests, plus support for multiple amplifier devices simultaneously.
SignalGeneration — Hardware
External UFI control expansion
Hardware upgrade enables external control of additional UFI devices — expanding interruption testing capacity for complex multi-interface ECUs.
