Table 12: Input voltage present at oscilloscope using different attenuators
The P1202 field source's measurement output can be used to calculate the magnetic flux density
B
generated by the field source at the position of the test IC.
The voltage equivalent of the pulse current i
p
has to be measured at the field
source’s
measurement output for this purpose. The respective field quantities can then be calculated using
the conversion factor defined in Table 13.
B = K1 ∙ i
