Stored patterns

The STEVAL-IME003V1 offers the possibility to memorize 16 patterns into on-board Flash

memory in order to show the performance achievable at the pulser outputs. Six selectable

patterns already stored in the Flash memory are preset by default, available and ready to

use. A detailed description of the preset programs is listed in the tables that follow.
