Hi Cypress
In the AN85951-CapSense design Guide.pdf, chapter<7.6.1.2.1 Device Operating Voltage>, Figure7-43. By the spectrometer, Test the performance of the signal, I want to know : which signal (or which PIN is the signal draw from) is tested by the spectrum analyzer? From the Capsense Sensor?
Thanks!

Hi,
We have followed the spec IEC 61000-6-3:2006.
- We configured say 5 buttons in the validation board and setup with some configuration such as VDD/CapSense HW parameters. Clocks etc..,
- Then the device with battery powered is placed in the Anechoic room
- There will be a receiver antenna which receives this EM signal radiated from the device and plots that data using spectrum analyzer.
