Output

To Test

Power supply transients can affect AC

measurements. Simultaneous transitions

of multiple outputs should be avoided for

accurate measurement. Threshold tests

must not be performed under AC

conditions. Large-amplitude, fast-ground-

current transients normally occur as the

device outputs discharge the load

capacitances. When these transients flow

through the parasitic inductance between

the device ground pin and the test system

ground, significant reductions in

observable noise immunity can result.
