Figure 6. Far-eld antenna conguration utilizing internal sources from the Legacy (E836xC)
PNA Option H11.
Figure 7. Far-eld antenna conguration utilizing internal sources with PNA-L Option 216,
PNA Option 201, PNA-X standard.
If the range allows the use of ampliers instead of a PSG, you can take advantage of the
excellent frequency agility of the PNA/PNA-X which minimizes the frequency switching
time for far-eld measurements congurations. See Figure 6.
