How to get physical conversion rate from mdf4

Question

How can I extract the conversion factor and offset for the signals of an mdf4 file. I am using asammdf, but I couldn't figure out, from where it gets the information e.g. when I use the mdf.to_dataframe(raw=False) method.

Answer 1

This information cannot be aprt of the dataframe. Instead you should extract just the required channel and look at the conversion attribute

from asammdf import MDF
m = MDF(file)
ch = m.get('MySignal', raw=True)
print(ch.conversion)
