When a Sensor Passes Every Test Except One, Every Single Time!
An inductive position sensor was failing ISO 11452-4 Bulk Current Injection(BCI) testing between 20 and 30 MHz consistently. Repeated filtering attempts weren't moving the needle. The team needed to understand why it was failing, and not just where before they could fix it. SimYog's virtual EMC lab recreated the entire BCI environment, identified the responsible resonant coupling mechanism, and enabled engineers to evaluate multiple filter configurations without touching the hardware once.
When a Chip Keeps Shutting Down, and the Lab Can't Tell You Why
An automotive High-Side Driver IC was failing radiated immunity testing across three frequency bands. The protection circuitry was tripping, but the root cause remained hidden. Using SimYog’s Compliance-Scope®, a virtual EMC laboratory, engineers identified the exact susceptibility path, reduced coupled voltage from 14 V to 0.35 V, and achieved a passing design before another board iteration.
