In this episode of Scopes University, we’ll be showing you how to test your NFC-enabled components with an oscilloscope. You can think of NFC like a short-range version of radio-frequency identification (RFID). NFC uses electromagnetic fields (induction), between two devices to enable communication between them. Passive NFC components store data that can be read by active NFC components. Active components can read and send information.

NFC communication often involves financial transactions, like paying for groceries, and security information, like clearance badges. NFC is even being used by automotive manufacturers to replace car keys. Therefore, reliable and secure communication is a must. You can gain peace of mind that your designs meet quality and reliability requirements by debugging and testing the physical layer of your NFC designs. Using oscilloscope software is a great way to perform fast, low-cost NFC pre-compliance tests during design or even manufacturing to make sure quality is being maintained.
Johnnie Hancock, our InfiniiVision product manager, is going to show us how to trigger on events like SENS and ALL Requests, test frame delay, demodulate the response and polling signals, and make frequency domain measurements to look at the carrier and side frequency of the response.

If you want to follow along on your InfiniiVision oscilloscope, you can download a free trial of the NFC Triggering and Automated Test Software here: https://www.keysight.com/main/editorial.jspx?id=3050878&cc=US&lc=eng .
