information may result. Figure 2-32 shows an example of phase samples with AC#J less than HO0
and greater than 180°.
Undersampling may arise when measuring devices with long electrical length. To correct this
problem, the frequency span should be reduced, or the number of points increased until Ad is
less than 180° per point. Electrical delay may also be used to compensate for this effect (as
shown in the next example procedure).
