Built for complex platforms, UAD3+ handles multicore and multi-board setups where synchronized control is essential. Its modular pod and connector system lets you mix protocols per core or target and still keep everything in lockstep using dedicated hardware and firmware synchronization.

For demanding trace workflows, UAD3+ supports industry protocols like Aurora and CoreSight ETM, with plug-in pods that keep wiring simple and reliable even when the base unit sits up to 5 meters away. Deep on-board memory, precise time stamping, and wide trace streams help capture rare events and long scenarios without gaps. Optional galvanic isolation and extended voltage ranges make it suitable for inverter, motor, and other high-voltage environments.
