audio and functional test points and limits
The A2DP Bluetooth audio and functional test uses a sine wave signal to check the
frequency accuracy, amplitude accuracy, flatness, and THD+N ratio for the analyzer and
generator.
shows the test points as well as the associated test limits for the maximum A2DP
audio bandwidth (48 kHz sample rate).
