| + | ==== Calibration ==== | ||
| + | Because the slope and intercept of the system vary from device to device, a system level calibration is **required**. | ||
| + | - Apply two known signal levels PIN_1 and PIN_2 close to the endpoints of the AD8318 linear input range. Note that it should be well within the linear operating range of the device (**-50 dBm to -10 dBm for this device**){{ : | ||
| + | - Measure the corresponding output codes CODE_1 and CODE_2 from the ADC | ||

| + | * **SLOPE_ADC** = (CODE_2 - CODE_1)/ | ||
