Sebopeho
•E fana ka likhetho tse tharo bakeng sa li-modulator tsa IQ format e ikemetseng:
•QPSK, QAM, OFDM, SSB e netefalitsoe
•Hokela le ho Bapala:
Ha ho na calibration ka letsoho e hlokahalang Ntho e 'ngoe le e' ngoe e iketsang
•I, Q arms: taolo ho mefuta ea Peak le Null Karolelano e phahameng ea pheliso: 50dB max1
•P letsoho: taolo ho mekhoa ea Q+ le Q- Ho nepahala: ± 2◦
•Boemo bo tlase: 40mm(W) × 28mm(D) × 8mm(H)
•Botsitso bo phahameng: Kemiso ea dijithale ka botlalo Ho bonolo ho e sebelisa:
• Ts'ebetso ea matsoho ka jumper e nyane e Flexible OEM e sebetsa ka UART2
• Mefuta e 'meli ea ho fana ka li-voltage tsa bias: a.Automatic Bias Control b.User defined bias voltage

1 Polar e ipapisitse le lets'oao la RF la sistimi. Ha ho se na lets'oao la RF tsamaisong, polar e lokela ho ba ntle. Ha lets'oao la RF le na le amplitude e kholo ho feta boemo bo itseng, polar e tla fetoha ho tloha ho e ntle ho ea ho e mpe. Ka nako ena, Null point le Peak point li tla chenchana.Q+ point le Q-point li tla chenchana hape.Polar switch e thusa mosebelisi ho fetola polar.
