1.
Full scale of EPP2/EPN2 is lower than full scale of EPP1/EPN1 but the default gain is the same.
3.14dBm0 will lead to clipping if the default gain is used.
2.
The idle channel noise was measured with digital zero signal fed to decoder. This can be realized by set-
ting outCalibrate and sideTone to 0 during a call.
3.
The test signal is a 1 kHz, 0 dbm0 sine wave.
4.
This is the frequency response from a highpass and lowpass filter combination in the DAC of the ba-
seband chip set. If the PCM interface is used, this filter is not involved in the audio path. Audio mode 1
to 4 incorporate additional frequency response correction filters in the digital signal processing unit and
are adjusted to their dedicated audio devices (see
