Perform EMC validation and robustness testing with a low-cost, portable bench top unit. Our CAN-based LVTGO-VBS family of low-voltage battery simulators allows you to easily perform robustness and validation testing as well as EMC standards testing. Tests to standards published by JLR, Ford, VW, BMW, GM, Fiat Chrysler and Mercedes Benz or any published standard are performed.
LVTGO waveforms include cranking and stop/start voltages, voltage dropouts, fast transient burst noise (FTBN), and other waveforms. Major published standards are included in the library and others can be easily added.
Exhaustive Testing
Exhaustive testing goes beyond standards testing and is included with all LVTGOs. Exhaustive testing uses randomization techniques and is about testing for those unexpected conditions not normally tested for and, therefore, not found. Randomization allows you to not only do exhaustive testing, but also zero in on areas of interest. This substantially increases test coverage and results in a much more robust system design prior to production.
Test runs can be run unattended overnight, over weekends or longer.
Exhaustive testing subjects ECUs to a lifetime of fault conditions over and above basic standards.
