1 Polar e fa'alagolago ile fa'ailoga RF system. Afai e leai se faʻailoga RF i le faiga, e tatau ona lelei le polar. A faʻaalia le faʻailoga RF e sili atu nai lo se tulaga, o le polar o le a suia mai le lelei i le leaga. I le taimi nei, o le Null point ma le Peak point o le a fesuiai le tasi ma le isi. O le Q+ point ma le Q-point o le a fesuia'i le tasi ma le isi. Polar switch e mafai ai e le tagata fa'aoga ona sui le
polar tuusa'o e aunoa ma le suia o galuega.

1 Na'o le tasi le filifiliga e tatau ona filifilia i le va o le fa'aogaina o le photodiode pule po'o le fa'aogaina o le photodiode modulator. E fautuaina le fa'aogaina o le photodiode e pulea mo su'esu'ega a le Lab mo mafuaaga e lua. Muamua, o le pule o le photodiode ua faʻamautinoa uiga lelei. Lona lua, e sili atu ona faigofie le fetuutuunai o le malosi o le malamalama. Afai e fa'aogaina le photodiode i totonu o le modulator, fa'amolemole ia mautinoa o le gaosiga o lo'o i ai nei o le photodiode e matua'i fa'atatau i le mana fa'aoga.
