lxi-tools

Build Status Snap Status

1. Introduction

lxi-tools is a collection of open source software tools that enables control of LXI compatible instruments such as modern oscilloscopes, power supplies, spectrum analyzers etc.

All features are consolidated in the 'lxi' application which provides a simple commandline interface to discover LXI instruments, send SCPI commands, and capture screenshots from supported LXI instruments.

Also provided is a GUI application which provide some of the features of the commandline tool.

lxi-tools rely on liblxi for all communication.

2. Usage

2.1 lxi-gui (BETA)

The lxi-gui application provides some of the same features as the commandline tool but presents them in a GUI frontend.

2.2 lxi

The commandline interface of the lxi application is described in the output from 'lxi --help':

     Usage: lxi [--version] [--help] <command> [<args>]

       -v, --version                        Display version
       -h, --help                           Display help

     Commands:
       discover [<options>]                 Search for LXI devices
       scpi [<options>] <scpi-command>      Send SCPI command
       screenshot [<options>] [<filename>]  Capture screenshot
       benchmark [<options>]                Benchmark

     Discover options:
       -t, --timeout <seconds>              Timeout (default: 3)
       -m, --mdns                           Search via mDNS/DNS-SD

     Scpi options:
       -a, --address <ip>                   Device IP address
       -p, --port <port>                    Use port (default: VXI11: 111, RAW: 5025)
       -t, --timeout <seconds>              Timeout (default: 3)
       -x, --hex                            Print response in hexadecimal
       -i, --interactive                    Enter interactive mode
       -s, --script <filename>              Run script file
       -r, --raw                            Use raw/TCP

     Screenshot options:
       -a, --address <ip>                   Device IP address
       -t, --timeout <seconds>              Timeout (default: 15)
       -p, --plugin <name>                  Use screenshot plugin by name
       -l, --list                           List available screenshot plugins

     Benchmark options:
       -a, --address <ip>                   Device IP address
       -p, --port <port>                    Use port (default: VXI11: 111, RAW: 5025)
       -t, --timeout <seconds>              Timeout (default: 3)
       -c, --count <count>                  Number of request messages (default: 100)
       -r, --raw                            Use raw/TCP

2.2.1 Example - Discover LXI devices on available networks

     $ lxi discover
     Searching for LXI devices - please wait...

     Broadcasting on interface lo
     Broadcasting on interface eth0
         Found "RIGOL TECHNOLOGIES,DS1104Z,DS1ZA1234567890,00.04.03.SP2" on address 10.42.1.20
         Found "RIGOL TECHNOLOGIES,DP831,DP8F1234567890,00.01.14" on address 10.42.1.67
     Broadcasting on interface wlan0

     Found 2 devices

2.2.2 Example - Send SCPI command to an instrument

     $ lxi scpi --address 10.42.1.20 "*IDN?"
     RIGOL TECHNOLOGIES,DS1104Z,DS1ZA1234567890,00.04.03

To dump response to file simply do:

     $ lxi scpi --address 10.42.1.20 "*IDN?" > response.txt

2.2.3 Example - Capture screenshot from a Rigol 1000z series oscilloscope

     $ 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

2.2.4 Example - Capture screenshot and convert it to any image format

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 screenshot image to JPG:

    $ lxi screenshot --address 10.42.1.20 - | convert - screenshot.jpg

2.2.5 Example - List available screenshot plugins

     $ lxi screenshot --list
