Kodi Mumadziwa Zokhudza Ma Scanner a Digital?

Monga Mawonekedwe Okhazikika Oyesa Pamsewu, Scanner Yapa Digito Imawonetsadi Malo Opanda Mawaya a Malo Oyesera.Imagwiritsidwa Ntchito Pakuyesa kwa CW (Continuous Wave) Signal Testing, Network Optimization Road Testing, ndi Network Optimization Work for Room Distribution Systems.

Tiyeni Tiyang'ane Pama Parameter Wamba Ndi Mfundo Za Nthawi Ndi Gawo La Digital Scanner Kuti Tisokoneze Kufufuza.

Ma Parameter Ofunika A Scanner Yapa digito Akuphatikiza Zokonda Zam'kati, RBW (Resolution Bandwidth) Zokonda, Zikhazikiko Zakukula Kwa Band, Etc.

Mfundo Yakukhazikitsa kwa Internal RF Attenuator Ndi:

(1) Pamene Kuli Kofunikira Kusaka Zizindikiro Zing'onozing'ono, Mtengo Wochepetsera Uyenera Kukhazikitsidwa Monga Momwe Kungathekere, Apo ayi, Chizindikiro Chofufuzidwa Chidzamezedwa Ndi Phokoso Lapansi La Frequency Scanner Ndipo Sitingawoneke;

(2) Pakafunika Kuzindikira Zizindikiro Zamphamvu, Mtengo Wochepetsera Uyenera Kukhazikitsidwa Momwe Ungathere, Kupanda kutero Zidzayambitsa Kupotoza Kopanda Mzere M'dera la Scanner, Kuwonetsa Zizindikiro Zabodza, Ndipo Ngakhale Kuwononga Mawonekedwe;

Mfundo Zokhazikitsa RBW Ndi:

(1) Pofufuza Zizindikiro Zing'onozing'ono za Narrowband, Mtengo wa RBW Uyenera Kukhazikitsidwa Mochepa Momwe N'zotheka, Apo ayi, Chizindikiro Chofuna Kusaka Chidzaphatikizidwa Ndipo Sichitha Kusiyanitsa, Ndipo Ngakhale Kumezedwa Ndi Phokoso La Scanner Ndi Kusawoneka Konse;Koma Ngati Mtengo wa RBW Ndiwotsika Kwambiri, Nthawi Yosesa Idzakhala Yotalika Kwambiri Ndipo Mphamvu Yoyesera Idzakhudzidwa;

(2) Poganizira Kuti Bandwidth Ya RB Imodzi Ya GSM Signal, PHS Signal Ndi TD-LTE Yayandikira 200K, Ndipo Mphamvu Yoyesera Yonse, Ndikofunikira Kuti RBW Ya Scanner Ikhazikitsidwe Ku 200KHz.

Mfundo Yokhazikitsa Kukula kwa Frequency Band Ndi:

(1) Kupyolera mu Fyuluta Cooperation, Khazikitsani Frequency Band Scale ku LTE System Bandwidth Scale Kuti Mufufuze Zosokoneza Zomwe Mumagwirira Ntchito, Monga F-Band TDS In-Band Interference, GSM Second Harmonic Interference, ndi DCS Intermodulation Interference.Ndikoyenera Kulumikiza Zosefera Zofananira za Frequency Band Mukasesa pafupipafupi.Mwachitsanzo, F-Band Scrambling Investigation Yakhazikitsidwa Ku 1880-1900MHz.Mukasesa Pafupipafupi, Doko Lililonse La Mlongoti Litha Kulumikizidwa Ku RRU, Kulumikiza Zosefera, Ndi Kulumikiza Khomo Lotulutsa Zosefera Ndi Frequency Scanner;

(2) Sesani Mabandi Apamwamba Ndi Otsika Oyandikana ndi Bandi Yamafupipafupi Kuti Mufufuze Ngati Pali Ntchito Zosiyanasiyana za Siginecha Pamagulu Ang'onoang'ono Osiyanasiyana.Mwachitsanzo, Mukafufuza Kusokoneza Kwa F-Band, Mutha Kukhazikitsa Scale ya Sweep Frequency Band 1805MHz-1920MHz, ndikufufuza 1805-1920MHz Payokha.Malinga ndi Signal And Intensity Of 1830MHz, 1830-1850MHz, 1850-1880MHz, And 1900-1920MHz Frequency Band, Fufuzani Mphamvu Ya Chizindikiro Cha DCS Molingana ndi Kusokoneza Waveform Kuti Muthandize Kudziwa Ngati Pangakhale Kusokoneza Kwathunthu Ndi DCS;

Kuphatikizira Zomwe Zikusokoneza Mu Band Ndi Kusokoneza Kwakunja Kwa Band Kwa Kumtunda ndi Kumunsi Kwafupipafupi Pamasitepe Awiri Pamwambapa, Ndizotheka Kusanthula Zolemera Zosiyanasiyana Zosokoneza Pamalo Osokoneza Pomwe Zosokoneza Zambiri Zimachitika.
