When setting up a lab scope to measure a waveform ranging from 0 to 15 volts with eight vertical divisions, what must the voltage level be set at?

When using a lab scope to measure a waveform, determining the voltage per division is critical for accurate waveform representation. In this case, you need to measure a signal that ranges from 0 to 15 volts and have a display with eight vertical divisions.

To determine the appropriate voltage level of each division, you divide the total voltage range by the number of divisions. Here, the calculation would be 15 volts divided by 8 divisions, which equals 1.875 volts per division. Rounding this value to a practical setting on the oscilloscope, selecting 2 volts per division ensures that the entire 15-volt range can be clearly displayed within the confines of the oscilloscope's vertical resolution.

Choosing 2 volts per division allows you to have enough headroom for the 15-volt maximum while ensuring that the entire signal is effectively displayed without distortion or clipping. This configuration also aids in easier interpretation of the waveform interacting within that voltage range.
