The high-resolution, dual channel, visible and near-infrared spectrographCARMENES offers exciting opportunities for stellar and exoplanetary research onM dwarfs. In this work we address the challenge of reaching the highest radialvelocity precision possible with a complex, actively cooled, cryogenicinstrument, such as the near-infrared channel. We describe the performance ofthe instrument and the work flow used to derive precise Doppler measurementsfrom the spectra. The capability of both CARMENES channels to detect smallexoplanets is demonstrated with the example of the nearby M5.0 V star CD Cet(GJ 1057), around which we announce a super-Earth ($4.0\pm0.4\,M_\oplus$)companion on a 2.29 d orbit.
