[tfcollins]

Need naming and doc updates

[tfcollins]

Remove the channel suffix here (_altvolt0) to all the related properties as it doesn’t provide much value

[tfcollins]

Add docstrings for all public properties

[amiclaus]

v2:

• drop _altvolt0 suffix
• add docstrings

[amiclaus]

rebase with main branch to get the build fixes.
