When designing embedded wireless technologies for worldwide deployment, it’s important to consider the different regional regulatory requirements. Radio regulations vary around the world for some of the frequencies most attractive for unlicensed radio control and telemetry. For some applications, standardized radios operating at 2.4 GHz (Bluetooth, ZigBee, or Wi-Fi) can be used almost anywhere in the world. For other applications, the greater building penetration, less interference, and lower power consumption of lower frequency radios may be more attractive. This application note will demonstrate the use of the Tektronix MDO4000 Series Mixed Domain Oscilloscope in the design, verification and optimization of radio ICs for the same application, but two different geographic regions—Europe and North America.
