CONFIGURATION REGISTER 19 ADDRESS (26h) R/W AGC CONTROL 6
Bits 7:5
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Bits 4:0
AGC Lock-in level (0-7.5 range)
CONFIGURATION REGISTER 20 ADDRESS (28h) R/W AGC CONTROL 7
Bits 7:5
R/W, But Not Used Internally
Bit 4:0
AGC Lock Window (0-15.5 range)
CONFIGURATION REGISTER 21 ADDRESS (2Ah) R/W AGC CONTROL 8
Bits 7,6
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Bits 5:0
AGC Threshold (0-31.5 range)
CONFIGURATION REGISTER 22 ADDRESS (2Ch) R/W AGC CONTROL 9
Bits 7,6
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Bits 5
AGC Look up table read control bit
1 = Read
0 = write
Bits 4:0
AGC lookup table address (32 address bits)
CONFIGURATION REGISTER 23 ADDRESS (2Eh) R/W AGC CONTROL 10
Bits 7
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Bits 6:0
AGC look up table data unsigned
CONFIGURATION REGISTER 24 ADDRESS (30h) R/W AGC CONTROL 11
Bits 7
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Bit 6:0
AGC loop gain (0.xxxx - 1.0000 range)
CONFIGURATION REGISTER 25 ADDRESS (32h) R/W AGC CONTROL 12
Bits 7
AGC RX_RF, This input drives the RF RF control if AGC override Enable is set to 1
Bits 6:0
AGC RX_IF, This reg is input to RF IF DAC if AGC override Enable is set to 1
CONFIGURATION REGISTER 26 ADDRESS (34h) R/W AGC TEST MODES
Bits 7:4
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Bit 3
AGC run on freeze- AGC keeps running after acquisition is complete, only signal is updated, no changes to IF or RF gain occur
0 = normal
1 = enabled
Bit 2
AGC override Enable, if set, CR25 controls receiver gain in both RF and IF
0 = normal
1 = enabled
Bit 1
AGC random I/Q allows random data on AGC 6 bit I/Q inputs if PN is enabled
0 = normal
1 = enabled
Bit 0
AGC test math- always accumulates in gain adjust, always outputs mean power from log table.
0 = normal
1 = enabled
