-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.+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 feedback loop is defined by the Gain vs. Frequency plot shown above. ƒ<sub>I</sub>, ƒ<sub>D</sub> and ƒ<sub>HF</sub> define three corners in the transfer function. ƒ<sub>I</sub> is the frequency where the gain switches from having integral gain to having proportional gain. ƒ<sub>D</sub> is the frequency where the gain switches from proportional to differential. ƒ<sub>HF</sub> is the frequency where the gain begins to fall off at high frequency. ƒ<sub>I</sub>, ƒ<sub>D</sub>, and ƒ<sub>HF</sub> are each controlled by a rotary switch. The feedback loop is defined by the Gain vs. Frequency plot shown above. ƒ<sub>I</sub>, ƒ<sub>D</sub> and ƒ<sub>HF</sub> define three corners in the transfer function. ƒ<sub>I</sub> is the frequency where the gain switches from having integral gain to having proportional gain. ƒ<sub>D</sub> is the frequency where the gain switches from proportional to differential. ƒ<sub>HF</sub> is the frequency where the gain begins to fall off at high frequency. ƒ<sub>I</sub>, ƒ<sub>D</sub>, and ƒ<sub>HF</sub> are each controlled by a rotary switch.
