I think you should be able to get sigrok-cli to grab your data the way you want, with appropriate parameters. For example you should use --config data_source=Memory to grab the whole memory instead of just the visible screen. You can have a look a the driver source to get an idea of the options you can set: http://sigrok.org/gitweb/?p=libsigrok.git;a=blob;f=src/hardware/rigol-ds/api.c;h=1f784cfce344177d997a08d5fc73e5a8f0f8e76a;hb=HEAD#l639 > So I used > a script that directly opens a TCP/IP connection on the LXI port and > followed the Rigol DS2000 Programming Guide. > > What is described in the PDF and what I see on the oscilloscope differs > a WHOLE lot, so therefore I figure someone on here might be able to help > me.

Not sure why you didn't go straight to the latest version (03.04): http://beyondmeasure.rigoltech.com/acton/fs/blocks/showLandingPage/a/1579/p/p-001a/t/page/fm/0 > Big mistake, now it really doesn't work at all anymore :-( Here's > a log hexdump: http://pastebin.com/jbGkQ9P7 Works for me (simply using netcat): $ nc 192.168.1.150 5555 *IDN?

Let us know if you manage to do what you want, and tell us what improvement you would need from sigrok for your use case. Feedback is always useful.
