Automask Menu
The Automask menu contains the selections used to generate the upper and
lower limit masks at defined tolerances using the data from a selected source.
Masks are generated and stored in waveform memory pairs m1 and m2 or m3
and m4.
Automask Softkey
The automask softkey generates the upper and lower limit mask for the
selected source waveform at the specified tolerance. Each mask is stored in
the selected nonvolatile memory pair.
Once an automask is generated, the previous contents of the selected
memory pair are overwritten. Any data previously stored is lost.
Prior to performing an automask, verify that the data for the selected source
is valid, the source selected is set to on, the destination memories are not
protected, and the horizontal and vertical tolerance are specified.
Make sure you set the source---memory, tolerance units, and
horiz-vert softkeys correctly. Otherwise, the mask may not generate, or
it may generate incorrectly.
Copy Scaling Softkey
The copy scaling softkey copies the scaling information from the
selected source to the specified nonvolatile mernory pair. Both the source
and the memory pair are selected using the source---memory softkey.
You can use the copy scaling feature when you plan to make
measurements on the mask or make comparisons to the mask.
