Analog filter and demodulator for Electromagnetic (EMA-RF) and Radio Frequency Analysis (RFA) on contactless solutions (ISO/IEC 14443)


When testing for side channel leakage in a contactless solution, the 13.56 MHz carrier wave of the reader introduces significant noise in the measurements. The CleanWave consist of analog filters that reduce the RF signal while preserving the leakage signal from the contactless smart card. As a result, the input voltage range of the digital oscilloscope can be reduced which leads to a reduction of the quantization error and consequently to a better signal to noise ratio. While the CleanWave is designed to be used in combination with the Inspector EM probe for EMA-RF or Micropross MP300 TCL2 RF antenna for RFA, the filter can be used with any side channel test system.
