Gabatarwar katin hoto na Universal Comprehensive Test

Universal Comprehensive gwajin graphics katin TE105 don yau da kullun (gani) kimantawa na 16: 9 TV kyamarori.Yana kunshe da zagaye tsari, launin toka sikelin, lattice na wedge layi, waveband sassa, lattice, diagonal da kuma kwance layi.

Matsayi na 4 na launin toka yana ƙaruwa daga D = 0.15 zuwa D = 1.65. Haɗa 25/15 grid daidai da lantarki grid janareta.

An tsara zane-zane na gwaji don kimantawa na canja wurin kyamarar lantarki. Ana amfani da zane-zane mai zagaye da grid a cikin hoton don kimanta ƙididdigar lissafi. An rarraba 2MH da 4MHz line grids a duk faɗin yankin hoto, tare da 4MHz grids suna karkata a kusurwar 45 ° da 135 ° a kwance.

Aiki tare da line zaɓi sauya oscilloscope, amfani da persistence tsaye grid don ƙayyade modulation zurfin mita amsa. A karkata 1MHz block a matsayin tunani darajar. Ƙarin amfani da persistence line grid zai iya ƙayyade ganewar gani na iyakar ƙuduri. Bugu da ƙari, don auna sakamakon tsangwama na launi, tacewar yawo da tacewar comb.
Bayanan watsa shirye-shirye na bayanan watsa shirye-shirye (stripes) da ke sama da ƙasa da abubuwan launin toka. A rough kimanta reproducibility na rabin launin tare da taimakon launin toka.

Akwai diagonals uku a cikin yankin murabba'in launin toka don ganowa na intersection. The matakala irin karɓar layi nuna twisted layi. An sanya bands biyu a gefen hagu da dama, mitar gida ta kai 8 a gefen hagu da 16MHz a gefen dama.

An yi amfani da bands a kan hoton don ƙayyade wadannan fasali na TV kyamarori da TV watsa shirin:
1, ƙuduri a kwance, tsaye da kuma diagonal
2, ƙuduri ya dogara da wurin da aka bincika
3, m da kuma tsaye aperture gyara sakamakon
4, tsangwama tasiri tsakanin kwalliya da kuma TV raster daidai launi video tube inuwa tsari
5, kwance da kuma tsaye (ko a gwajin zane) motsi amsa na kyamara: m ƙuduri, wucin gadi rikice-rikice
