Average emission measurements were calculated with PK DETECT and Duty cycle factor. * Duty Factor was calculated with the assumption of the worst condition in 100msec. * The result is rounded off to the second decimal place, so some differences might be observed. *The limit was converted from V to dBuV, and it is rounded off to the second decimal place. *Except for the above table : All other spurious emissions were less than 20dB for the limit. The carrier level (or, noise levels) was (or were) measured at each position of all three axes X, Y and Z, and the position that has the maximum noise was determined. With the position, the noise levels of all the frequencies was measured.
