Each installment will focus on a different oscilloscope-related topic. This week it’s measuring a test signal and probing Alternating Current ... and the trace drawn on the screen is seen ...

Figure caption, Oscilloscope trace of the voltage from an alternating supply. The signal is constantly changing value between positive and negative. The current changes direction 100 times per ...

To determine peak voltage from an oscilloscope trace, the maximum vertical deviation of the trace from the centre line is measured from the screen. This number of divisions is multiplied by the Y ...
