Amplitude sweep based method (amplitude range 1–2mT) 20 Hz 0.139 0.128
100 Hz 1.543 1.740
200 Hz 2.180 2.216
1000 Hz 715.702 434.720
Frequency ranges: Error Std. (%) Error mean (%)

Frequency sweep based method (amplitude 50mT) 290–2100 Hz 0.364 0.093
2110–3000 Hz 0.011 0.050
3000–4000 Hz 0.019 0.026
