AGC mid Sat counts (0-15 range) these are the counts to kick in the attenuator steps (CR28).
AGC low Sat Count (0-15 range)
Unused, set to 0
AGC timer count (number of clocks in AGC cycle, 32-63 range). Note: Timer count must be > 31.
AGC high sat attenuation (0-30). Note: hi sat attenuation step is actual value programmed times 2. This attenuation step will
occur if the # of I and Q saturations is greater than hi sat count.
AGC hi sat count (0-15 range)
CW detector scale multiplication factor. (xxxx.x). See CR35 for forcing default weights.
AGC Lock-in level (0-7.5 range)
R/W, But Not Used Internally
AGC Lock Window positive side (0-15.5 range). Note: outer lock window.
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
AGC Backoff (xxxxx.x, 0-31.5 range)
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
AGC Look up table read control bit
1 = Read AGC table at address given below
0 = Read contents of CR23
AGC lookup table address (32 address bits)
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
AGC look up table data unsigned
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
AGC loop gain (0.xxxx - x.00000, 0 - 1.0000 range)
AGC RX_RF, This input drives the RX-RF control if AGC override Enable is set to 1
AGC RX_IF, This reg is input to RF-IF DAC if AGC override Enable is set to 1. When polarity bit is zero, a “1” removes 30dB
pad, a “0” inserts 30dB pad.
