Abstract
The present invention is directed to a method for generating a pulse sequence using a logging tool. A pulse programmer is provided for adaptively controlling the creation and application of a sequence of RF magnetic field pulses to an earth formation. In order to control the RF pulses, a portion of a memory device is partitioned into a plurality of tables and control information is stored in the tables. The pulse programmer creates the pulse sequence using information found in the memory device and the operating conditions of the tool. The structure of the partitioned memory device allows the pulse programmer to adapt and change the timing of the pulse sequences autonomously downhole.
