#SHFAGCTX – Handsfree TX AGC Value tuning

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.

<agc_compr_thres>

compression threshold. This is the energy threshold of the input above

which compression is applied. Meaningful range is 0x0 to 0x2580. This

parameter must be greater than agc_exp_thres.

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

<agc_compr_slope>

compression slope. This is the slope of the compressor gain when

compression is applied. Meaningful range is 0x8000 to 0xFFFF.

Value(agc_compr_sloop) = 65536 * X : X range is 0.50001 to 0.99999

Note:

these values are automatically saved in NVM.

AT#SHFAGCTX? Read command returns the current handsfree TX AGC values

#SHFAGCTX:

<agc_static_gain>,<agc_aig>,<agc_exp_thres>,<agc_exp_slope>,<agc

_compr_thres>,<agc_compr_slope>

AT#SHFAGCTX =? Test command returns the supported range of values of parameter

<agc_static_gain>,<agc_aig>,<agc_exp_thres>,<agc_exp_slope>,<agc

_compr_thres>,<agc_compr_slope>
