Abstract

PURPOSE:To ensure an automatic measurement of the bias margin with a simple poeration by adding the bias magnetic field which lowers in a stepped wave way from the high-bias magnetic field to the low-bias magnetic field to the bubble element and then plotting the magnetic field which is within a range in which the normal output is sent out from the bubble sensor.
