Source sentences:
text: More expensive oscilloscopes also have controls for trace rotation, beam finding, and automatic intensity and focus.
text: Since waveforms come in a wide variety of shapes, amplitudes and frequencies, oscilloscopes need to have a number of controls to adjust the display of the waveform so it can comfortably fit inside the viewport.
text: Remember that some controls differ between analog and digital oscilloscopes; your oscilloscope probably has controls not discussed here.
