  • Page 43: Calibration

    Once this calibration data is stored, the input measurement and the signal source can be adjusted back to the most accurate value. The LDS-Dactron system uses sigma-delta A/D and D/A converters and an anti-aliasing filter with a very high cutoff frequency. As a result, the amplitude characteristics of the input and signal source are not frequency dependent.
