Release v1.0 - http://dev.doredevelopment.dk/psu-sample/psu-sample-1.0.tar.gz

Requirements

Make sure the following dependencies are installed:

• lxi-control
• gnuplot
• tr

Install

1. Run 'make' to compile msleep util
2. Customize plot.cfg, psu-sample.cfg, and psu-sample.sh as needed

Note: The current psu-sample.sh script is based on sampling LXI output from a TTI PL155-P PSU. Depending on your PSU this output might differently formatted - if so you need to modify the psu-sample.sh script to rearrange the output so that that lines in the samples.log resembles the following output line format: <time> <amp> <voltage>

Usage

1. Run psu-sample.sh to start sampling data from remote PSU

Example
