Self-Calibration An onboard, 24-bit ADC and precision voltage reference are 

used to calibrate the DC gain and offset. The self-calibration 
is initiated by the user through the software and takes 
approximately 75 seconds to complete.

External 
Calibration

The External Calibration calibrates the VCXO, voltage 
reference, output impedance, DC gain, and offset. 
Appropriate constants are stored in nonvolatile memory.
