Developing a new RFID-based product? It's a task that calls for RF, timing and modulation measurements. You'll need a tool that can trigger on the transient events that signify RFID activity, then capture and analyze the dialogue between the Tag and the Interrogator. As well as a tool for modulation analysis, and perhaps one for compliance tests as well. Or you can use just one tool to do it all: the Tektronix Real-Time Spectrum Analyzer (RTSA).
