OSSD test
The following diagram illustrates the different times needed for OSSD tests.
Figure 13 - OSSD test
Where:
T1 (Test pulse width) = 115
s
T2 (Test period on single OSSDx) = 900 ms
T3 (Shift time between OSSD pairs) = 150 ms
T4 (Shift time between OSSDs) = 300 ms
OSSD 1/1 must be paired with OSSD 1/2.
OSSD 2/1 must be paired with OSSD 2/2.
OSSD 3/1 must be paired with OSSD 3/2.
