Capture Rigol MSO5074 Oscilloscope Display as a .bmp file, for MacOS, Linux and Windows

The Rigol MSO5074 Oscilloscope is a powerful multi-channel tool for the hobbyist and professional alike. It includes a USB port, but there's not much in the way of software support for Linux and macOS systems.

rigol_grab is a cross-platform Python-based script that lets you capture the contents of the Rigol Oscilloscope display to a .bmp file via USB or Ethernet connection, such as this:

Setup

The setup process assumes you already have git, Python and pipenv set up on your machine. In a shell window:

> cd <your chosen directory>
> git clone https://github.com/rdpoor/rigol-grab.git
> cd rigol-grab
> pipenv install

Running rigol_grab

First, plug the Rigol 'scope into your computer via USB cable or connect it to your network and note its IP address. Then, in a shell window use these commands for a USB connection:

> cd <your chosen directory>/rigol-grab
> pipenv shell
> python rigol_grab.py --auto_view

Or use these commands for an Ethernet connection (substitute your Rigol's own IP address):

> cd <your chosen directory>/rigol-grab
> pipenv shell
> python rigol_grab.py --auto_view --port 127.0.0.1

Note that the --auto_view argument will cause the .bmp file to be opened immediately using the default viewer for your system.

Options

rigol_grab.py accepts command line arguments:

--verbose: print additional information
--filename <filename.bmp>: specify the pathname of the saved .bmp file (default: rigol.bmp)
--auto_view: automatically open the .bmp using your system viewer
--port: IP address of the oscilloscope if using Ethernet instead of USB

Caveats

There are a few known bugs. Top scientists are investigating these issues and hope to have a fix. Or you can propose a fix with a pull request:

• The program always throws an error upon exiting. This appears to be benign.
• Once every two or three times, the .bmp data is corrupted. If this happens, just re-run the script.
• There's been zero testing on Linux systems. But it might work.
