Carrier Lead Gain
Mantissa (Acquisition)
These bits are the 4 fractional bits of the lead gain mantissa shown below.
Lead Gain Mantissa = 0 1. 2
-1
2
-2
2
-3
2
-4.
This format provides a mantissa range from 1.0 to 1.9375 for mantissa settings from 0000 to 1111 Binary.
Bit position 17 is the MSB.
13-9
Carrier Lead Gain
Exponent (Acquisition)
These bits set the lead gain exponent as given by:
Carrier Lead Gain Exponent = 2
-(32-E).
where E corresponds to the 5-bit binary value programmed here. Thus, a gain range from
2
-1
to 2
-32
(relative to the MSB position of the NCO control word) may be achieved for E = 11111 to 00000
Binary. Bit position 13 is the MSB.
8-5
Carrier Lag Gain
Mantissa (Acquisition)
Format same as lead gain mantissa. Bit position 8 is the MSB.
4-0
Carrier Lag Gain
Exponent (Acquisition)
Format same as lead gain exponent. Bit position 4 is the MSB.
