Power Measurement

This demo uses the Analog Discovery Pro's Oscilloscope to measure the power of an RC circuit. Because the oscilloscope only measures voltages, a sensing resistor is used with the Oscilloscope's Math channels to calculate the current passing through the circuit and further the power of each component.

Decoding a Manchester Encoded Signal

The Logic Analyser instrument in WaveForms can be used to easily decode Manchester encoded signals. The following guide presents what Manchester encoding is, what are its advantages over unencoded digital signals and how to decode such a signal using the Logic Analyser instrument in WaveForms and a Test & Measurement device in a simple loop-back configuration.

Automated Measurement

Analog Discovery Pro also operates in a Linux mode. In this mode, the ADP boots into a terminal-based Linux distribution from Debian installed on the device. This allows to run automated test scripts written in Python, C, C++, C#, or Visual Basic through the APIs of the WaveForms SDK without a host computer. The Analog Discovery Pro acts then as an embedded device and adds additional flexibility and connectivity.
