Doesn't anyone here use EasyWave? If so, perhaps one of you might provide a response to my question posted on 4/2 (post #304).
Windows is banned from my lab, mostly due to the fun around a particular chip vendor committing corp suicide while trying to fight off chip clones so I don't run it but I have been digging in trying to figure out how to just upload waveforms without their software.
It may not be an answer but hopefully I can offer one soon. The actual wave files seem to only contain waveform data, in a very basic format. If the voltage settings are tracked they are in a file called "SDG200X_Arb_Summary_v1.2.xlsx" which is an E-SafeNet locked file.
As this is the only .xlsx file on the filesystem it may be that they are not saving settings for custom Arb file types, but I would highly encourage you to file a bug report, and to get them to change their model. I highly doubt anyone is going to try to pilfer their file format, and I bet they could have a healthy 3rd party software pool which would be a much larger sales driver than their Easywave software is.
I'll make a note to update this thread if I get more information, if someone else doesn't solve the issue before I get time to look into it.
