Open Source Summit + Embedded Linux Conference Europe 2020

Laboratory instrumentation - voltmeters, oscilloscopes or GHz network analyzers - have evolved from purely analog boxes (1970s), to incorporating digital control with rudimentary connectivity (1980s), to embedded systems (1990s), and finally, to fully connected machines running desktop operating systems, greatly simplifying automation tasks, and the (finally) simple task of getting a data file onto another machine for deeper data analysis. In this session, we will review how a number common tools like the Raspberrry Pi and the Linux kernel’s Industrial Input Output (IIO) framework can be leveraged with directly connected Analog I/O to speed up the development process, whether the end goal is performing a one-off experiment, inclusion in production automated test equipment, or prototyping designs for standalone benchtop instruments. Examples to be covered include: 1. A DC to 6GHz, low-distortion, RF signal source 2. A 24-bit, ultra-precise DC measurement system 3. A precision voltage source with 1 part per million linearity.
