Calculating CMS & DRL Values
Posted: Mon Dec 17, 2018 5:15 pm
I'm in the process of writing my own acquisition software and had a question about CMS and DRL. I'm using speedmode 4, a water bucket test, and a signal generator, I get nice smooth curves in my data, so I know I have the buffers and calls correct thanks to the forum post: viewtopic.php?t=452. What I don't understand is how to reference the signals based on CMS/DRL. Those values don't seem to be a channel in the stream of data.
According to: https://www.biosemi.com/faq/cms&drl.htm, "we suppose it is 100uV" but if you always assume it's the same value, why do you connect it? Unless it is 100uv, and has to be connected to have that value maybe?
I'm more of a software developer than an electrical engineer, so I may be missing something. Just looking to see if a forum member could provide more concrete information.
Thanks!
