It is\nspecifically meant for .dlog files that were written to a USB stick by the\npower analyzer itself, so no Keysight software is required for analyzing them.\n\n![](https://finalrewind.org/projects/dlog-viewer/media/preview.png)\n\nMeasurements can be exported to CSV or plotted on-screen via matplotlib.  There\nis also support for changepoint detection to automatically identify changes in\nthe observed device behaviour. This is meant to work around a lack of digital\nsynchronization signals in the logged power traces.\n\nThis program is not affiliated with Keysight and has not been thoroughly tested, as I only have a singly type of power analyzer at hand.\nUse at your own risk.\n\n## Usage\n\nObtain a .dlog file e.g. by using the instrument's data logger feature.\ndlog-viewer options include:\n\n* plots showing voltage, current, or power over time (`--plot`),\n* simple statistics (`--stat`, `--skip`, `--limit`)\n* changepoint detectiong using the PELT algorithm (`--pelt`),\n* CSV export of raw measurements (`--csv-export`), and\n* JSON export of measurements and detected changepoints (`--json-export`).\n\nSee `bin/dlog-viewer --help` for details.\n\n## Dependencies\n\n* Python 3, numpy, matplotlib, xml.etree\n* Changepoint detection: python3-ruptures\n\n## References\n\nMirrors of the dlog-viewer repository are available at:\n\n* [Codeberg](https://codeberg.org/derf/dlog-viewer)\n* [ESS](https://ess.cs.uos.de/git/bkf/dlog-viewer)\n* [Finalrewind](https://git.finalrewind.org/derf/dlog-viewer)\n* [GitHub](https://github.com/derf/dlog-viewer)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fderf%2Fdlog-viewer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fderf%2Fdlog-viewer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fderf%2Fdlog-viewer/lists"}
