Thanks for this - I have wondered whether it was measured peak to peak or
plus/minus. It is never specified....

Adam


What you care about is peak to peak, since that is what shows up on an image.
Usually, that is how it is specified, although I have occasionally seen it given
plus/minus. If you are looking at someone else's spec, and it doesn't say, you
have no way of knowing for sure what they are actually measuring.
