Configuring channel (vertical) settings
Overview The channel settings configure how the waveform
appears in terms of vertical or voltage scale.
Position Sets the vertical position of the
waveform.
Scale Sets the vertical scale (volts per
graticule). Range: 5mV/div to 5V/div
CH on/off Turns the channel on or off.
Coupling Selects AC or DC coupling. The DC
coupling shows all signal elements,
while the AC coupling filters out the
DC component from the waveform.
Inversion Flips the waveform upside down.
Magnifica
‐tion Magnifies the displayed units (does not
magnify the real signal). The
magnification function is useful to
align the displayed with probe
attenuation (page
