Mask Formats
The mask only format loads the selected mask into the oscilloscope. Loading
both the mask and setup is a convenient method to make sure that the
scaling for the mask is correct. You would use the mask only selection in
cases when you do not want to change the present setup of the oscilloscope.
Figure 8-6 shows an example of a mask.
