DS1054Z tricks, less known or undocumented (Part 2)

DS1054Z is LXI compliant. What I like the most at any LXI ready instrument is that it can be operated over LAN without installing any drivers, and without any dedicated software.

Want to save a screenshot from your oscilloscope? You don’t need to install anything. No VISA, no IVI, no Rigol drivers, no UltraScope or any other application, nothing. Just plug the LAN cable, open a Terminal and type:

# save a screenshot from the oscilloscope's display to the file 'image.png'
echo ":DISPLAY:DATA? ON,OFF,PNG" | nc -w1 5555 | dd bs=1 skip=11 of=image.png

Now, this is beautiful, isn’t it? All the credit for the above command goes to S Clark, thank you!

Of course, you need to replace “” with your oscilloscope’s IP address, and it should work with any Rigol oscilloscope model from the series DS1000Z, DS2000, DS4000 and DS6000, not only the DS1054Z. It should also work under Windows using Cygwin, but I didn’t test it.

You can always use Telnet or Netcat (AKA ‘nc’) to send SCPI commands to any Rigol oscilloscope using the oscilloscope’s IP address and port 5555. Telnet is not recommended when binary data is expected because Telnet might mangle some characters (see RFC854 page 10). For text only it’s OK.

Netcat is safe for both text or binary data, and there is a free standalone Netcat for Windows that does not require any Cygwin installation. Please be advised that Windows might consider ‘nc’ as a potential threat and block it, so you need to add ‘nc.exe’ to the safe programs list in order to run it under Windows.
