 ===Error Signal (AC)===
-This is an unfiltered version of  Error Signal (DC) that is four times smaller, and has a DC offset.  When phase locked, the output is 1.6V+2.8<sup>mv</sup>/<sub>deg</sub>*θ, where θ is the phase-error in degrees. When in frequency mode, the output is 1.6V±1V*(1-f<sub>small</sub>/(2 f<sub>big</sub>)).

 **Coarse Gain (eight-position switch)**
-The COARSE GAIN sets the overall proportional gain of the circuit without changing the location of any corners or poles in the loop filter transfer function. The coarse gain adjusts in steps of 6 dB from 0 dB to -42 dB.
