The Paul trap with a rectangular driving field, known as digital ion trap (DIT) has been investigated by mapping the stability diagram, i.e., measuring the relative storage efficiency with respect to the trapping parameters, and comparison to the conventional Paul trap with harmonic guiding field. The results show that the performance of the DIT can be described in terms of the conventional trap, when the trapping parameters are redefined according to the zeroth and first order Fourier component of the driving field. The higher harmonics seem to have only little influence.
