No programming required.
Reserved. Set to 0 for proper operation.
These bits are the 4 fractional bits of the lead gain mantissa shown below.
Lead Gain Mantissa = 0 1. 2
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.
These bits set the lead gain exponent as given by:
Carrier Lead Gain Exponent = 2
where E corresponds to the 5-bit binary value programmed here. Thus, a gain range from
2
Binary. Bit position 13 is the MSB.
Format same as lead gain mantissa. Bit position 8 is the MSB.
Format same as lead gain exponent. Bit position 4 is the MSB.
No Programming required.
Reserved. Set to 0 for proper operation.
Format same as lead gain mantissa (see Table 24). Bit position 17 is the MSB.
Format same as lead gain exponent (see Table 24). Bit position 13 is the MSB.
Format same as lead gain mantissa (see Table 24). Bit position 8 is the MSB.
Format same as lead gain exponent (see Table 24). Bit position 4 is the MSB.
Reserved. Set to 0 for proper operation.
Sets carrier track sweep rate used during acquisition (see Frequency Sweep Block Section). Format
same as lead gain mantissa (see Table 24). Bit position 22 is the MSB.
Sets carrier track sweep rate used during acquisition (see Frequency Sweep Block Section). Format
same as lead gain exponent (see Table 24). Bit position 22 is the MSB. M = 0000,
E = 00000 is 2
Sets Frequency Error Gain. Format same as lead gain mantissa (see Table 24). Bit position 11 is the
MSB.
Sets Frequency Error Gain. Format same as lead gain exponent (see Table 24). Bit position 4 is the MSB.
