Notes: Bold text items indicate default settings. The number to send to the QT2640 is the index number in the leftmost column (0 – 15), not numbers from the
table. The QT2640 uses a lookup table internally to translate the indices 0 – 15 to the parameters for each function.
NRD is an exception: It can range from 0 – 254 which is translated from 1 = 0.5 s to 254 = 127 s with zero = infinity.
CFO_1 and CFO_2 are exceptions. Their values, ranging from 0 to 255, are used directly and without any translation.
