The readout noise of a H2RG HgCdTe NIR detector from Teledyne is measured at a temperature T=105 K. In a previous work, we have analysed the evolution of the readout noise as a function of the number of reads in terms of the frequency power spectrum of the noise with our in-house hybrid readout electronics. The new measurements with the SIDECARTM ASIC provided by Teledyne Imaging Sensors are compared to the previous ones. The noise power spectrum found can be used in a wide range of timing conditions and allows to predict quantitatively the 1/f effects arising from different time samplings. In contrast with most previous publications, we investigate the time properties of single pixel signals rather than the spatial correlations.
