Set command sets the handset RX AGC value tuning

Parameter:

<agc_static_gain>

precompressor static gain. This is the gain applied to the input samples

when static gain is enabled. Meaningful Range is 0x2000 to 0xFFFF.

Value(agc_static_gain) = 8192 כ 10^(X/20) : X range is 0 to 18 dB.

<agc_aig>

pre-compressor gain selection flag. Write 0xFFFF to enable adaptive

gain (static gain disabled). Write 0x0000 to enable static gain (adaptive

gain disabled).

Meaningful value is just 0x0000 or 0xFFFF.

<agc_exp_thres>

expansion threshold. This is the energy threshold of the input under

which expansion is applied. This parameter must be less than

agc_compr_thres.

Meaningful range is 0x0 to 0x2580. Write 0 to disable the expander.

Value(agc_exp_thres) = 128 כ (X+75) : X range is -75 to 0 dBm0mu

<agc_exp_slope>

expansion slope. This is the slope of the expander gain when expansion

is applied. Meaningful range is 0xFF01 to 0xFFF6.

Value(agc_exp_slope) = 256 * X : X range is -0.04 to -0.996.
