Affects: Y-axis of Y-vs-X trace amplitude graphs
Y-axis trace amplitude measurements are taken on each frame as the difference between the level at this sample point, and the level at a reference point for the Y-axis trace.
This parameter can be set by specifying the time offset from the start of the sweep. It can also be set visually, using the pointing device to indicate the time on the displayed sweep for the sample point (and the reference point).
