lxi-tools is a collection of open source software tools for managing network attached LXI compatible test instruments such as modern oscilloscopes, power supplies, spectrum analyzers etc.
Features include automatic discovery of test instruments, sending SCPI commands, grabbing screenshots from supported instruments, benchmarking SCPI message performance, and powerful scripting for test automation. Both a commandline tool and a GUI tool are available.
lxi-tools rely on liblxi for all communication.
LAN eXtensions for Instrumentation (LXI) is a standard developed by the LXI Consortium, an industry consortium that maintains the LXI specification and promotes the LXI Standard. The LXI standard defines the communication protocols for modern instrumentation and data acquisition systems using Ethernet.
Visit www.lxistandard.org for more details.
Please notice that lxi-tools is not affiliated with the LXI consortium - it is an independent open source community effort.
The lxi-gui application provides some of the same features as the commandline tool and more but presents them in a modern GUI frontend.
SCPI mode - easily explore SCPI features of your instruments
Search for instruments - using standard broadcast discovery or mDNS
Screenshot mode - easily grab display screenshots from supported instruments
Benchmark mode - measure the message response performance of your instruments
Script mode - program your LXI compatible instruments in a powerful clean cut Lua script environment
Script mode in action plotting voltage levels from a DC power supply to line chart and CSV/PNG files
The commandline interface of the lxi application is described in the output from 'lxi --help':

To dump response to file simply do:
$ lxi scpi --address 10.42.1.20 "*IDN?" > response.txt
$ lxi screenshot --address 10.42.1.20 --plugin rigol-1000z
Saved screenshot image to screenshot_10.42.1.20_2017-11-11_13:45:47.png
Or using plugin autodetection simply:
$ lxi screenshot --address 10.42.1.20
Loaded rigol-1000 screenshot plugin
Saved screenshot image to screenshot_10.42.1.20_2017-11-11_13:46:02.png
By default the format of the captured screenshot image is dictated by which screenshot plugin and instrument are in play. However, it is possible to write the screenshot image to stdout and pipe it directly to other tools for image processing.
For example, use ImageMagicks convert tool to automatically convert any screenshot image to JPG:
$ lxi screenshot --address 10.42.1.20 - | convert - screenshot.jpg
$ lxi screenshot --list
