MODE_REG[12] should be set to 0 (= 6 dB gain) if the level of the FM2-carrier processed in MSP-Ch1 is appr. 7 dB below the FM1-carrier of

MSP-Ch2. If both carriers have the same level, MODE_REG[12] must be set to 1 (=0 dB gain).

MODE_REG[13]: If in MSP-Channel 1 and 2 the same bandwidth is required, it is sufficient to transmit FIR_REG2 only and to set

MODE_REG[13] to 1.

For compatibility (besides the above programming), the FIR-filter programming as used for the MSP 3410B is also possible.

ADR coefficients are listed in the DRP-data sheet.

The 130 kHz coefficients are based on subcarriers, which are 7 dB below an existent main carrier.
