4 Audio Analyzer Measurement Functions

SINAD measurement

SINAD (Signal, Noise, and Distortion Ratio) is equal to the reciprocal of the distortion
measurement. It is mostly used to determine the sensitivity of a communications receiver.
The ratio computed in the SINAD measurement is shown as follows.
SINAD
SINAD measurement function mode is applicable for the analog, digital, and Bluetooth
audio analyzer. The settings for SINAD measurement are displayed as shown in
Figure 4-24, Figure 4-25, and Figure 4-26 for the analog, digital, and Bluetooth analyzer
respectively.
