DS1221A Режекторный фильтр и демодулятор

When testing for side channel leakage in a contactless solution, a reader’s 13.56 MHz carrier wave introduces significant noise during measurement. The Notch Filter and Demodulator consists of analog filters that reduce the radio frequency signal while preserving the leakage signal from a contactless smart card. As a result, you can reduce the input voltage range of the digital oscilloscope to minimize the quantization error and consequently achieve a better signal-to-noise ratio. While the DS1221A is designed to be used in combination with the High Precision Electromagnetic Probe​ for electromagnetic radio frequency analysis or Micropross MP300 TCL2 RF antenna for radio frequency analysis, the filter can be used with any side channel test system.
