This read-write object sets the demodulator's acquisition sweep range in KHz, up to +/-32 KHz at symbol rates below 625 ksym/s or up to +/-200 KHz at higher rates. Identical in function to cdd564RxAcquisitionSweepWidth, this compensates for frequency uncertainty from LO drift, Doppler shift, or minor frequency-plan mismatches during the acquisition process, with a wider setting improving the odds of locking onto a slightly mistuned carrier at the cost of a longer search time and a small risk of locking onto an unwanted adjacent signal. A link showing intermittent difficulty reacquiring lock after a brief outage, despite a stable steady-state frequency offset once locked, might benefit from widening this sweep width to help the demodulator find the carrier faster during reacquisition.
