The difference between vertical position and vertical offset
■
Vertical position is a display function that moves the waveform image on the
screen. Moving the signal on the screen does not change the ground (0 volt)
baseline level for that signal.
■
Vertical offset is a signal function that adds a DC voltage to the input signal
before the oscilloscope preamplifier. Adding this DC voltage moves, or
offsets, the signal from the ground (0 volts) level. You use offset to increase
the effective dynamic range of a signal.
For example, you can set the vertical offset to match the peak area of a
signal, use the Vertical Position knob to move the peak area to the center
graticule, and then set the Vertical Scale knob to smaller voltage/division
settings to look at more detail in that waveform peak area.
