ADRV9001 EVALUATION SYSTEM
Compensation: It is the process of compensating for the analog attenuation in the device (prior to the ADC) with a corresponding amount of
►
digital gain before sending the digital signal to the user. Gain compensation uses the digital gain to effectively undo the analog gain so that
the recipient signal from the receiver data stays constant. The digital gain effectively compensates for the analog attenuation.
Correction: It is the process of correction that uses the digital gain to make the gain steps more accurate. This ensures that the receiver gain

steps are accurate.

Transmitter Attenuation
Use the DGPIO pins for transmitter attenuation control. Assign the DGPIO pins for attenuation increment and decrement. Specify the step
►
size in the Attenuation Control tab. Set the default step size to 0.05 dB.
Transmitter PA Ramp
Use one of the AuxDACs to output a ramp to control an external power amplifier.
