What do you get when you combine a direct digital synthesis (DDS) chip, a power detector, and an Arduino? [Brett Killion] did make that combination and wound up with a practical network analyzer.

Presented below is a simple and cheap 433-Mz RF Sniffer ideal for testing/reverse-engineering most 433-MHz wireless devices. As you can see, the setup is on the Arduino ground with a 433-MHz receiver ...

which are all controlled via a single SPI bus with an Arduino. Each RF switch is activated in a pseudo-random sequence, changing the configuration of the panel 10,000 times in 100 ms. The signal ...
