The ground reference of the trace. Ground references are offset so that they do not overlap. The ground ref-
erence offset value is referenced to the horizontal center line of the grid.
Voltage trace labels appear on the left side of the grid (V1 and V2) as shown in the display.
Current trace labels appear on the right side of the grid (I1 and I2).
Power trace labels appear on the center of the grid (P1 and P2).
