The ThinkRF Real Time Spectrum Analyzer comes integrated with external GPIOs, I and Q output ports, among others. The external GPIOs consist of the external trigger feature, enabling

synchronized sweep setup to automate spectrum scanning and capture with the use of external hardware and/or multiple ThinkRF RTSA devices. Meanwhile, the I and Q output ports facilitate

integration with external high speed digitizers. This application note explains how to setup a synchronized sweep with signals feed to external I and Q output ports, as well as providing the

GPIO setup requirement.
