6.2.1 Me s rin pla
Before the UUT has be n in tal ed, a me s rin plan s ould b develo ed b sed on the
sp cification of the UUT an the region in whic the res lts are to b re orted The
Trang 18me s rin plan is b sed on the decision p ints in 6.2.2 throu h 6.2.9 These decision p ints
– automatic brig tnes control ca a i ties (6.2.7),
– automatic brig tnes control levels (6.2.8),
– network con ection ca a i ties (6.2.9)
When these decision have b en taken, the fol owin activities can b exp cted to b
