content: Hey guysI was testing the Record Mode on my Rigol and saved a .rcd file on my USB memory.To record a wave...Utility, Record, Mode Record, Operate.Then to save it to your USB memory...Mode Storage, Location External, Save.Now I have the file, how can I read it using my PC? I am attaching it to this message.The file contents are not in plain TXT.Thanks!

content: RCD format seems to be from the old series, DS1000E saves into WFM format, isn't it?For this last format there are some readers, and at RC groups someone tells about a reader for old scopes' files.

content: Yes, it can also save a screen in a WFM file, but it's only a screenshot.The RCD file seems to save more time, not only a printscreen.

content: The rcd file is only 8k in size. the wfm files seem to be 16k in size and contains 16k of data.Maybe the rcd file is compressed?I know the wfm files are not compressed and can be read easily with a good hex editor.I have attached a wfm file captured from a DS1102E showing the cal signal from the dso.Regards

content: Well, it could be a 8k sample file, 8 bits per sample. I don't remember how many 1ms samples I took.Tomorrow I will run another test.

content: the rcd file stores a series of frames of the signal at a parametrized interval, much like a video. To save the raw data you have to choose the WFM format in the Acquire menu, and then save to an internal or external location

content: Migsantiago, i cant seem to find anything that will open this file. The Rigol Scope software wont open it, maybe this file type is from an older generation. Have you considered updating the firmware on the scope? Newer firmware may allow you to save as a WFM file.Regards

content: Quote from: Darkman1969 on November 07, 2010, 01:00:30 amHi man.I've always been able to save as a WFM file, no problem with that.I just wanted to test this RCD file and see if there was more info from it than from a WFM file.
