11 APD Measurement
Marker
Delta
Sets the control mode for the selected marker to Delta and turns on the active function for setting its delta
value. If the selected marker is off, the marker is placed at the beginning of the trace.
In Delta mode, the marker result shows the relative result between the selected (Delta) marker and its
reference marker. A delta marker can be moved to any point on the X Axis by specifying its X Axis offset
from a reference marker. Its absolute Y Axis value is then the value of the trace point at that X Axis value.
