Test V. PDL/PDG uncertainty (#020 only)
The absolute PDL/PDG uncertainty is the maximum value of
several PDL measurement when changing the alignment of the
PDL generating components.
1 Set up and switch on the equipment:
a Connect the equipment as shown in Figure D-6.
(Set-up for performing the test with Head Input A. For
