Ngā tikanga whakamātautau mō te mahi a te kaiwhakatikatika hiko-whatu

Ngā tikanga whakamātautau mō te mahi akaiwhakarerekē hiko-whatu

1. Ngā taahiraa whakamātautau ngaohiko haurua-ngaru mōte whakarerekētanga kaha hiko-whatu

Hei tauira, ko te ngaohiko haurua-ngaru i te pito RF, ka honoa te pūtake tohu, te taputapu kei raro i te whakamātautau me te oscilloscope mā roto i tētahi taputapu ara-toru. Ina whakamātautauhia te ngaohiko haurua-ngaru i te pito Bias, honoa kia rite ki te rārangi iraira.

b. Whakakāhia te pūtake mārama me te pūtake tohu, ka whakamahia he tohu ngaru niho kani (ko te auau whakamātautau noa he 1KHz) ki te taputapu kei te whakamātautauhia. Me nui ake te tohu ngaru niho kani Vpp i te rua o te ngaohiko haurua-ngaru.

c. Whakakāhia te oscilloscope;

d. Ko te tohu putanga o te pūoko he tohu kosinī. Tuhia ngā uara ngaohiko ngaru niho kani V1 me V2 e rite ana ki ngā tihi me ngā awaawa e tata ana o tēnei tohu. e. Tātaihia te ngaohiko haurua-ngaru e ai ki te Tātai (3).

2. Ngā taahiraa whakamātautau mō te ngaohiko haurua-ngaru okaiwhakarerekētanga wāhanga hiko-whatu

I muri i te hononga o te pūnaha whakamātautau, me noho te rerekētanga ara whatu i waenga i ngā ringa e rua e hanga ana i te hanganga interferometer whatu ki roto i te roanga honohono. Ka honoa te pūtake tohu me te pito RF o te taputapu kei raro i te whakamātautau me te hongere 1 o te oscilloscope mā te taputapu ara-toru. I muri i te hononga o te pūnaha whakamātautau, me noho te rerekētanga ara whatu i waenga i ngā ringa e rua e hanga ana i te hanganga interferometer whatu ki roto i te roanga honohono. Ka honoa te pūtake tohu me te pito RF o te taputapu kei raro i te whakamātautau me te hongere 1 o te oscilloscope mā te taputapu ara-toru, ā, ka whakatikatikaina te tauranga whakauru o te oscilloscope ki te āhua ātete-teitei.

b. Whakakāhia te taiaho me te pūtake tohu, ka tāpirihia he tohu ngaru niho kani o tētahi auau motuhake (te uara noa 50KHz) ki te taputapu kei raro i te whakamātautau. Ko te tohu putanga o te pūoko he tohu kosine. Me nui ake te Vpp o te tohu ngaru niho kani i te rua o te ngaohiko haurua-ngaru, engari kaua e neke atu i te awhe ngaohiko tāuru kua tohua e te kaiwhakatikatika, kia whakaatu ai te tohu kosine putanga o te pūoko i te iti rawa i te kotahi huringa katoa.

c. Tuhia ngā uara ngaohiko ngaru niho kani V1 me V2 e pā ana ki ngā tihi me ngā awaawa e tata ana o te tohu kosinī;

d. Tātaihia te ngaohiko haurua-ngaru e ai ki te Tātai (3).

3. Te ngaronga whakaurunga o ngā whakarerekētanga hiko-whatu

Ngā taahiraa whakamātautau

I muri i te honotanga o te pūtake mārama me te polarizer, whakakāhia te pūtake mārama ka whakamātautau i te mana whatu tāuru Pi o te taputapu e whakamatautauria ana me te mita mana whatu.

b. Honoa te taputapu e whakamatautauria ana ki te pūnaha whakamātautau, ka honoa ngā pito putanga o te pūhiko hiko kua whakaritea ki ngā pine 1 (GND) me te 2 (Pītaha) o tekaiwhakarerekē(mō ētahi puranga o ngā pūwhakarerekētanga, me hono hoki te pine 1 o te pūwhakarerekētanga ki te whare).

c. Whakatikatikahia te ngaohiko putanga o te pūtake hiko kua whakaritea, ka whakamātauria te pānui mōrahi o te mita hiko whatu hei Pout.

d. Mena he taputapu whakarerekētanga ā-wāhanga te taputapu e whakamatautauria ana, kāore he take ki te tāpiri i tētahi pūtake hiko whakaū ngaohiko. Ka taea te pānui tika i te Poutū mai i te mita hiko whatu.

e. Tātaihia te ngaronga whakaurunga e ai ki te Tātai (1).

Ngā Whakatūpato

a. Kaua te tāuru whatu o te pūwhakarerekētanga hiko-whatu e neke ake i te uara whakatikatika i runga i te pūrongo whakamātautau; ki te kore, ko teKaiwhakarerekē EOka pakaru.

b. Kaua te tāuru RF o te pūwhakatikatika hiko-whatu e neke ake i te uara whakatikatika kei runga i te pepa whakamātautau; ki te kore, ka pakaru te pūwhakatikatika EO.

c. I te wā e whakatū ana i tētahi ine whakawhiti, he nui ngā whakaritenga mō te taiao whakamahinga. Ka pā pea te wiri o te taiao me te nekeneke o te muka whatu ki ngā hua o te whakamātautau.
