R1-1.3 Unbuffered Test Data Acquisition
R1-1.3.1 This scenario shows acquisition of test results data from the test equipment while test is being performed
on the device(s). This scenario is useful for online process analysis. Note that all test data for current device(s)
under test needs to be read and acknowledged before next unit can proceed since data will be unbuffered.
Table R1-1 Unbuffered Test Data Acquisition Scenario
Host Test Equipment
SC introduces lot to equipment and other
external systems.
Tester completes PP-SELECT and in READY state.
SC configures Test Data Collection plan on
Tester and issues START command. See
Test Result Data Collection section for
details.
Assume Data Set A is assigned to all
Testheads.

R1-1.4 Buffered Test Data Acquisition
R1-1.4.1 This scenario shows acquisition of test results data using the buffered approach. The buffered test data log
is read at the end of entire lot processing. How the buffered data is being stored on tester is implementation specific.
Table R1-2 Buffered Test Data Acquisition
Host Test Equipment
SC introduces lot to equipment and other
external systems.
Tester completes PP-SELECT and in READY state.
SC configures Test Data Collection plan on
Tester and issues START command. See

When all units for lot have been processed,
before ending the lot, SC requests all
buffered data from tester …
Note: This transfer step can be skipped if file
is shared on network. In this case, just copy
the file and reset the dataset.
