Signal Chain: an engineer’s instrument log
An RF and embedded-instrumentation engineer documents hardware, firmware, and signal-processing projects, including tools for VLF lightning detection.
- For
- RF and embedded-instrumentation engineers
- Worth noticing
- The project list spans a three-channel GNSS-timed acquisition unit and PPS timing comparisons at nanosecond resolution.
Field notes
The project index connects measurement hardware to its intended field use: one acquisition unit is described as the core of a VLF lightning direction-finding station. Other entries cover real-time dual-channel VLF acquisition and a web-based ground-station digital twin for ionospheric TEC measurements. The author’s latest listed log entry describes an initial attempt to pull raw waveforms from a Hantek oscilloscope into Python.
