• 一般注記: The high-resolution magnetic field measurement in the intense field is required for the achievement of the Arase project. The magnetometer (MGF) onboard Arase has the digital resolution of 20 bit, which is realized by the 20-bit analogue-to-digital conversion (ADC). A delta-sigma ADC circuit has been developed to satisfy the 20-bit resolution, 256 Hz sampling and tolerance for the severe radiation environment in the radiation belt. We performed the ground experiment at a room temperature to evaluate the non-linearity characteristics of the delta-sigma ADC used for MGF. The non-linearity error for the full range was measured by obtaining continuously the output digital values from ADC for gradually varying input analogue voltage. The maximum non-linear error was 781 digits (0.07% of the full range) corresponding to 11 nT (84 nT) for +/-8000 nT (+/-60000 nT) measurement range. The deviation was determined within 103 digits, corresponding to 1.5 nT (11.0 nT) for +/-8000 nT (+/-60000 nT) range, when the environmental interference noise was not intense. It is within 213 digits, corresponding to 3.1 nT (22.5 nT) for +/-8000 nT (+/-60000 nT) range, when the environmental noise was significant.; 形態: カラー図版あり; Physical characteristics: Original contains color illustrations; 資料番号: AA1830033002; レポート番号: JAXA-RR-18-005E
