EMC immunity tests

The STEVAL-IFP010V3 has been tested according to EMC immunity standards

IEC61000-4-4 (fast transient burst) and IEC61000-4-5 (high energy surge).

A fast transient burst test has been performed all channels.

Each channel under test cycles on and off at 1 Hz, duty cycle 50%, on two 48

A burst signal was applied using an ultra-compact simulator with an internal capacitive

coupling clamp tool.
