Mask Testing
Run Until The Run Until softkey lets you specify a condition on which to terminate testing.
• Forever — The oscilloscope runs continuously. However, if an error occurs the
action specified using the On Error softkey will occur.
• Minimum # of Tests — Choose this option and then use the # of Tests softkey
to select the number of times the oscilloscope will trigger, display the
waveform(s), and compare them to the mask. The oscilloscope will stop after
the specified number of tests have been completed. The specified minimum
number of tests may be exceeded. If an error occurs the action specified
using the On Error softkey will occur. The actual number of tests completed
is displayed above the softkeys.
• Minimum Time — Choose this option and then use the Test Time softkey to
select how long the oscilloscope will run. When the selected time has passed
the oscilloscope will stop. The specified time may be exceeded. If an error
occurs the action specified using the On Error softkey will occur. The actual
test time is displayed above the softkeys.
• Minimum Sigma — Choose this option and then use the Sigma softkey to
select a minimum sigma. The mask test runs until enough waveforms are
tested to achieve a minimum test sigma. (If an error occurs the oscilloscope
will perform the action specified by the On Error softkey.) Note that this is a
test sigma (the max achievable process sigma, assuming no defects, for a
certain number of tested waveforms) as opposed to a process sigma (which is
tied to the amount of failures per test). The sigma value may exceed the
selected value when a small sigma value is chosen. The actual sigma is
displayed.
