Kodi mukudziwa zenizeni zokhudzana ndi scanors digito?

Monga mawonekedwe oyeserera amsewu, scanner digito imawonetsera zingwe zopanda zingwe zoyeserera. Amagwiritsidwa ntchito mu cw (mafunde opitiliza) Kuyesa kwa SISTAL, kuyesa kwa msewu wa pa intaneti, ndi ntchito yotsatsa pa network yogawa chipinda.

Tiyeni tiwone magawo wamba ndi mfundo za nthawi ndi magawano a scanner ya digito kuti isokoneze kufufuza.

Magawo ofunikira a digito amaphatikiza makonda a Attenator, RBW (mabanki a bandwidth), makonda am'munda, etc.

Mfundo ya RF yamkati ndi iyi:

.

.

Mfundo za RBW ndi:

. Koma ngati ngati phindu la RBW ndi lotsika kwambiri, nthawi yasesa idzakhala lalitali kwambiri ndipo mphamvu yoyesera idzakhudzidwa;

.

Kukula kwa band band

. Ndikofunika kulumikiza zosefera zofananira zofananira pafupipafupi mukamawononga pafupipafupi. Mwachitsanzo, kafukufuku wa F-band amafufuza za 1880-1900mhz. Mukamasesa pafupipafupi, doko lililonse la antenna limasambitsidwa ku Rru

. Mwachitsanzo, mukafufuza zosokoneza za F-band, mutha kukhazikitsa sepa pafupipafupi gulu la 1805mhz-1920mhz, ndikufufuza 1805-1920Mz payokha. Malinga ndi chizindikiro ndi mphamvu ya 1830mhz, 1830-1850mhz, 1850-18808080mhz, ndi 1900-190mhz mobwerezabwereza kuti zithandizire kudziwa ngati pali DC Scarse ndikusokoneza kwathunthu;

Kuphatikiza mikhalidwe yolumikizirana ndi zosokoneza bongo ndi zosokoneza bongo zapamwamba kwambiri m'masitepe awiri omwe ali pamwambawa, ndizotheka kusanthula miyeso yosiyanasiyana yosokoneza bongo pomwe zosemphana kangapo.
