Overview. Use this control to turn the margin mode on or off and to set the percentage of margin used for the mask test.
To use.
1. Click the On/Off button to turn the mask margin tolerance on or off.
2. Click the up and down arrows or click in the Margins entry box to activate the pop-up keyboard and set the percentage of
margin tolerance.
Behavior. When the mask margin tolerance is on, you can control the percentage of margin used in the mask test.
Use the up and down arrow buttons to increase or decrease the percentage in 1% increments. A tolerance that is > 0 makes
passing a mask test more difficult.
A mask test that passes with a tolerance that is > 0 demonstrates that the signal passes the test with a margin for further error.
Setting the tolerance to < 0 makes a mask test easier to pass. A tolerance that is < 0 can be used to demonstrate by how much
of a margin the signal fails.
