GW Instek GDS-1062A - Expand Vertical Scale Center; Ground; Inverting the Waveform Vertically

CONFIGURATION
71
AC coupling mode. Only the AC
portion of the signal appears on the
display. This mode is useful for
observing AC waveforms mixed with
DC components.
Expand Vertical Scale Center / Ground
Background
Normally when the vertical scale is increased, the
scaled image is centered from ground. However a
signal with a voltage bias could be obscured when
the vertical scale is increased. The Expand Center
function expands the image from the center of the
signal, rather than ground.
