The Leveled Sine Wave Function
The Leveled Sine Wave (Levsine) function uses a leveled sine wave, whose amplitude
remains relatively constant over a range of frequencies, to check the oscilloscope’s
bandwidth. When you check your oscilloscope, you change the wave’s frequency until
the amplitude displayed on the oscilloscope drops 30 %, which is the amplitude that
corresponds to the -3 dB point.
To access the Levsine menu, press the softkey under MODE until “levsine” appears.
