1 Ko te Polar e whakawhirinaki ana ki te tohu RF punaha. Mena kaore he tohu RF i roto i te punaha, me pai te polar. Ka nui ake te kaha o te tohu RF i tetahi taumata, ka huri te polar mai i te pai ki te kino. I tenei wa, ka huri te tohu Null me te Peak point tetahi ki tetahi. Ko te tohu Q+ me te tohu-Q ka huri tetahi ki tetahi. Ko te whakawhiti polar ka taea e te kaiwhakamahi te huri i te
polar tika me te kore e huri i nga tohu mahi.

1 Kia kotahi anake te kowhiringa i waenga i te whakamahi i te photodiode kaiwhakahaere, te whakamahi ranei i te photodiode modulator. E taunaki ana kia whakamahia te photodiode kaiwhakahaere mo nga whakamatautau Lab mo nga take e rua. Tuatahi, kua whakapumauhia e te photodiode kaiwhakahaere nga kounga. Tuarua, he ngawari ake te whakatika i te kaha o te rama whakauru. Mena kei te whakamahi i te photodiode o roto o te modulator, me mohio kei te tino rite te putanga o te photodiode ki te mana whakauru.
