The dc charge current, field induced spin polarization, and spin textures are studied in the one-dimensional gated superlattice with both fixed and varying Rashba and Dresselhaus contributions to spin-orbit coupling. It is found that a spin component with zero mean value can demonstrate nonvanishing field induced spin texture in a superlattice cell which can be probed experimentally, with the highest amplitudes achievable in an interval of comparable Rashba and Dresselhaus terms. The consideration of the finite parameters for collision rate and temperature is found to be nondestructive for the calculated current and spin characteristics depending on all states below the Fermi level.
