NOTES:
3. Unless otherwise noted, the analog input is 0 dB, 1020-Hz sine wave, where 0 dB is defined as the zero-reference point of the
channel under test.
4. The reference signal level, which is input to the transmit channel, is defined as a value 3 dB below the full-scale value of 88 mVrms.
The transmit channel gain is 24 dB (External gain is 18 dB, the default setting for the TXPGA is 0 dB and microphone amplifier is
set to 6 dB).
