Hello,

Yes. The performance of CapSense (raw counts) gets affected during CI and RI tests. The performance degradation depends on the magnitudes and frequencies of signals used in the tests. However, if the designer follows the design rules mentioned in the following application note perfectly, the affects of EMI/EMC on the CapSense performance can be minimised.

Hope this information helps!

Thanks and regards
