1 Polar inoenderana nechiratidzo cheRF chesystem. Kana pasina chiratidzo cheRF musystem, polar inofanira kunge yakanaka. Kana chiratidzo cheRF chine amplitude yakakura kupfuura imwe level, polar ichachinja kubva pane yakanaka kuenda kune negative. Panguva ino, Null point nePeak point zvichachinjana. Q+ point neQ- point zvichachinjana zvakare. Polar switch inobvumira mushandisi kuchinja
polar zvakananga pasina kuchinja nzvimbo dzekushanda.

1 Sarudzo imwe chete ndiyo inofanira kusarudzwa pakati pekushandisa controller photodiode kana kushandisa modulator photodiode. Zvinokurudzirwa kushandisa controller photodiode pakuedza kweLab nekuda kwezvikonzero zviviri. Chekutanga, controller photodiode ine hunhu hwayo. Chechipiri, zviri nyore kugadzirisa simba rechiedza chinopinzwa. Kana uchishandisa photodiode yemukati memodulator, ndapota iva nechokwadi chekuti simba rekubuda kwephotodiode rinoenderana nesimba rinopinzwa.
