2 Press Grid; then, turn the Entry knob to change the intensity of the
displayed grid.
The intensity level is shown in the Grid softkey and is adjustable from 0
to 100%.
Each major vertical division in the grid corresponds to the vertical
sensitivity shown in the status line at the top of the display.
Each major horizontal division in the grid corresponds to the sweep
speed time shown in the status line at the top of the display.
Accumulating multiple acquisitions
Turning off infinite persistence does not clear the display. This allows you to accumulate
multiple acquisitions, stop acquisitions, and then compare future acquisitions to the stored
waveforms. The display is cleared if you press the Clear Display softkey or if you press the
[AutoScale] key.
