Mode SBM1 avec les paramètres suivants pour le waveform picker:
// 2688 = 8 * 336
waveform_picker_regs->nb_data_by_buffer = 0xa7f; // 0x30 *** 2688 - 1 => nb samples -1
waveform_picker_regs->snapshot_param = 0xa80; // 0x34 *** 2688 => nb samples
waveform_picker_regs->start_date = 0x00; // 0x38
waveform_picker_regs->nb_word_in_buffer = 0x1f82; // 0x3c *** 2688 * 3 + 2 = 8066

On attend pour intervalle de temps entre deux buffers full à f1 2688 samples / 4096 = 0.65625 s = 43 008 T_fine

On relève 43 180 T_fine entre deux buffers (différence calculée sur les valeurs coarse time et fine time directement prélévées dans deux buffers successifs).

La modification d'un paramètre dans le design VHDL 0.0.F, 250 devient 249, résoud le problème.
