Figure 3–71: Creating a User Mask
To create a mask with a concave side, create several masks to cover the same
area.
Masks are saved with setups, so you can save sets of masks by defining
them, and then storing the instrument setup. Displayed masks are overwrit-
ten when you recall a stored setup, select a standard mask, or initialize the
digitizing oscilloscope.
