Creating a New User Mask
To create a new user mask that is not based on an existing mask, do the following procedure.
Set instrument settings
1. Use the communications trigger features to trigger the
instrument on a signal. The instrument saves these settings
with the mask information.
Create an empty user
mask
2. From the button bar, click Masks, and select the Masks tab.
3. Click the User Mask button.
4. Click the mask standard field to display the drop-down list.
5. Select None from the list.
6. Click the Copy Current Mask to User Mask button. If you
are asked if you want to overwrite the current user mask,
click the Yes button.
Create an edit new mask
segments
7. Click the Edit User Mask button to display the user mask
edit functions.
8. Click the Segment field, and use the arrow buttons,
multipurpose knob, or keypad to enter or select segment 1.
9. Click the Vertex Add button. The instrument draws the
default new segment shape, a triangle.
10. Use the instructions on Editing a User Mask on page 341,
starting at step 5 to edit a segment.
11. Repeat steps 9 through 11, selecting an unused and
sequential segment number, to create and edit more
segments.
Save the user mask to
disk
12. See Saving a User Mask to Disk procedure on page 342.
You do not need to save the user mask to disk, because the
instrument retains the current user mask in nonvolatile memory.
However, if you plan to create a number of user masks, you will
need to store the user masks on disk or the hard drive, because the
instrument can load only one user mask at a time.
