Tsim qhov me me oscilloscope. Zaus ntau yog txog 40KHz (25uS puv npo) Hauv 4 qib xaiv tau. Cov tswv yim hluav taws xob nyob nruab nrab ntawm 50mVpp thiab 50Vpp hauv 2 qhov kev xaiv xaiv. Kev nce tau yog kho tau ntawm 1 txog 100. Txais AC lossis DC cov tswv yim. Nws pib-ua haujlwm cheb kom "khov" cov duab yoj. Kev cheb dawb tau los ntawm kev teeb tsa lub hwj chim ntawm ob qho teeb meem. Y-axis hloov kho rau nruab nrab nthwv dej. Khiav los ntawm roj teeb 9V.
