Average Noise Level (DANL)” on page 46
a. DANL is specified in the narrowest resolution bandwidth (1 Hz) with log averaging, in accordance with
industry and historic standards. The effect of log averaging is to reduce the noise level by 2.51 dB. The
effect of using a 1 Hz RBW is to increase the measured noise because the noise bandwidth of the 1 Hz
RBW filter is nominally 1.056 Hz, thus adding 0.23 dB to the level. The combination of these effects
makes the sensitivity, in units of dBm/Hz, 2.27 dB higher than DANL in units of dBm in a 1 Hz RBW.
