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 ow through the
parasitic inductance between the device
ground pin and the test system ground,
signicant reductions in observable noise
immunity can result. Numbers in
