     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.

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