Abstract:
A series of measurements taken during different drive conditions on the General Standards 18 bit DAC card. This measurement extends to lower frequencies, the measurement taken in T0900338. This result is in reasonable agreement with the earlier result in T0900338. An analog twin-tee filter was used to notch out sinusoidal excitation at 100.58Hz. The effect of this filter has been compensated in the 1_to_800_corrected_withBaseline.pdf plot
