Oscilloscope Dual Trace

Taifuka: A cikin oscilloscope dual trace, tushen elektron mai yawa maimakon biyu, wadanda suka shiga da daliban biyu. Don samun waɗannan furfurubu biyu, an amfani da hanyoyi biyu: na alternate da na chopped. Su ne kuma ake kira hanyoyin switch.

Wannan ya haɗa tambaya: Me kana iya buƙatar wannan oscilloscope?

A lokacin da ake bincike ko karɓar al'adu daga manyan fagarurwa, ita ce muhimmi ga a duba voltagashin. Yawancin ake iya amfani da manyan oscilloscopes. Amma, bayanin canza sweep daga bako da bako ba shi ba zama abin da ke fiye.

Idan haka, za a iya amfani da oscilloscope dual trace. Ya yi amfani da tushen elektron mai yawa maimakon biyu.

Block Diagram and Working of Dual Trace Oscilloscope

Na barazan ya nuna block diagram ta oscilloscope dual trace:

Working Principle of Dual - Trace Oscilloscope

Kamar yadda aka gani a barazan, oscilloscope dual trace ya fi siffar dalibi masu yawan biyu, kamar Channel A da Channel B.

An sa shugaban ruwa da kuma siffar dalibi biyu kan biyu. An sa shugaban ruwa da kuma siffar dalibi biyu zuwa electronic switch. Wannan electronic switch ya ba shugaban ruwa daga channel mafi girma a lokacin daɗi.

An yi don trigger selection switch a cikin circuit, wanda ya ba a tabbata bayanin Channel A, bayanin Channel B, ko bayanin da ake fito shi.

Bayanin daga horizontal amplifier ya iya ba electronic switch ta hanyar sweep generator ko Channel B ta hanyar switches S0 da S2.

Hakan, vertical signal daga Channel A da horizontal signal daga Channel B ana ba Cathode - Ray Tube (CRT) don a yi aiki a cikin oscilloscope. Wannan shine X - Y mode ta oscilloscope, wanda ya ba a tabbata X - Y measurements masu inganci.

Fiye, aikin oscilloscope ya ɗaukar zabe-zaben kontrol a cikin panel na maza. Misali, idan ake buƙata waveform daga Channel A, idan ake buƙata waveform daga Channel B, ko idan ake buƙata waveforms daga Channel A ko B zuwa baki ɗaya.

Kamar da ake magana, akwai hanyoyi biyu don oscilloscope dual trace. Daga baya, za a iya duba hanyoyi biyu masu yawan biyu.

Alternate Mode of Dual - Trace Oscilloscope

Idan ake fara alternate mode, yana ba aikin Channel A da Channel B a matsayin alternates. Wannan alternation ko switching daga Channel A zuwa Channel B ya faru a farkon har scan.

Kuma, akwai nasara a cikin rate ta switching da rate ta sweep. Wannan ya ba a tabbata waveform daga kowace channel a cikin scan ɗaya. Misali, waveform daga Channel A za a tabbata a cikin scan ɗaya, kuma a cikin scan na biyu, Cathode - Ray Tube (CRT) za a tabbata waveform daga Channel B.

Daga baya, alternate connection daga input biyu zuwa vertical amplifier ya faru.

Electronic switch ya faru daga channel mafi girma zuwa channel mafi girma a lokacin fly - back period. A lokacin fly - back period, tushen elektron ya bashi, saboda haka, channel-to-channel switch ya faru.

Saboda haka, scan ɗaya za a tabbata signal daga channel mafi girma a cikin screen, kuma a cikin scan na biyu, signal daga channel mafi girma biyu za a tabbata.

Na barazan ya nuna output waveform ta oscilloscope a lokacin da ya yi aiki a cikin alternate mode:

Kamar da ake magana, akwai hanyoyi biyu don oscilloscope dual trace. Daga baya, za a iya duba hanyoyi biyu masu yawan biyu.

Alternate Mode of the Dual - Trace Oscilloscope

Idan ake fara alternate mode, yana ba aikin Channel A da Channel B a matsayin alternates. Wannan alternation ko switching daga Channel A zuwa Channel B ya faru a farkon har scan.

Kuma, akwai nasara a cikin rate ta switching da rate ta scan. Wannan ya ba a tabbata waveform daga kowace channel a cikin scan ɗaya. Misali, waveform daga Channel A za a tabbata a cikin scan ɗaya, kuma a cikin scan na biyu, Cathode - Ray Tube (CRT) za a tabbata waveform daga Channel B.

Daga baya, alternate connection daga input biyu zuwa vertical amplifier ya faru.

Electronic switch ya faru daga channel mafi girma zuwa channel mafi girma a lokacin flyback period. A lokacin flyback period, tushen elektron ya bashi, saboda haka, channel switching ya faru.

Saboda haka, scan ɗaya za a tabbata signal daga channel mafi girma a cikin screen, kuma a cikin scan na biyu, signal daga channel mafi girma biyu za a tabbata.

Na barazan ya nuna output waveform ta oscilloscope a lokacin da ya yi aiki a cikin alternate mode:

A cikin wannan mode, electronic switch ya yi aiki a matsayin frequency masu yawan biyu, kamar 100 kHz zuwa 500 kHz. Kuma, frequency ta electronic switch ya ɗauke da frequency ta sweep generator.

Saboda haka, a cikin haka, segments mafi girma daga biyu channels za a iya ba amplifier.

Idan chopping rate ya fi yawa da horizontal sweep rate, segments mafi girma za a juye da juye don a yi waveforms na Channel A da Channel B a cikin screen ta Cathode - Ray Tube (CRT).

Amma, idan chopping rate ya fi kadan da sweep rate, za a iya ba discontinuity a cikin display. Saboda haka, a cikin haka, alternate mode ya fi yawa.

Oscilloscope dual trace ya ba a tabbata zabe-zaben operation modes ta hanyar panel na maza.
