An engineer at work was working a project a couple months ago, wherein he acquired a bunch of RS-422 data using a digital oscilloscope. They’re CSV files, and quite large (around 117 MB).
The engineer abruptly quit to become a comedian. (I am not making this up.) I was tasked to pick up the pieces on the project. I need to “decode” the RS-422 data he acquired.
So I tried bringing up one of the files in Excel. Two problems:
The version of Excel I have at work is limited to 1 million rows.
I tried plotting some of the data (X-Y chart). It is incredibly slow.
So what do I do? Is there better software?
