噪聲密度譜和累積噪聲（單通道）

The outstanding noise performance of the LNHR DACII is shown here. This plot shows the noise density spectrum (red) and the integrated noise (blue) at 0 V, 5 V, and 10 V output and the low-bandwidth setting (BW=100 Hz). Data for high bandwidth setting (100k Hz) is shown in the user manual. For this specific measurement, the integrated noise from 0.1 Hz to 100 Hz ~170 nVrms at 0 V output; even better than the 300 nV stated in the table above . The European mains-frequency of 50 Hz and some of its harmonics can be identified on the noise density spectrum . However, those peaks do not add significantly to the total noise voltage as seen on the integrated noise . For frequencies above 100 Hz the noise density drops due to 100 Hz LP-filter and reaches the noise floor of 1 nV/√ Hz at 900 Hz originating from the differential amplifier used for measurements.
