Tutorial 6: Test to Industry Standards
Turn Mask Testing On
6 Turn mask testing on by pressing:
Masks, test ON OFF ON
This resets the error counters. Errors for the standard specifications show up
beside the M1 screen annotation for mask violations, and beside L2 and L3 for
upper and lower limit violations, respectively.
Notice that in this case, violations are occurring due to too much overshoot.
Test with Additional Margin
7 Set a 15% mask margin and turn margin testing on by pressing:
mask setup, MASK MARGIN and enter 15, msk mar ON OFF ON
This displays a second set of mask and limit lines for the 15 percent margin.
Errors for the specifications with the specified amount of margin show up
beside the M4, L5 and L6 screen annotations.
The eye-diagram analyzer can count dot (trace point) errors instead of trace
errors. Use the count TRC DOT softkey to make the selection. If a given error
puts 12 trace points within the mask, then the error counter increments by 12.
This is useful for determining the extent of any given error. These features can
be used with either eye or eyeline modes.
