Test Setup
Figure 9.3 shows the application of dropout
simulations on signal and data lines up to 2 A,
where up to 16 lines individually or simultaneously
may be interrupted. The return lines of each pair
can be individually tested.
For higher current, like with T.31 (battery minus)
one may use S1N.

Test Case 1 Slow Interval
Each pin must be disconnected for
10 s
and then
reconnected (slow interval).
One could also perform this test manually with a
switch. However, use of the PFM 200N100.1
offers the capability of exactly 10 s, down to ms
accuracy, thus resulting in repeatable results.
