Table of Conversion Factors

To determine the measured magnetic flux density (sometimes called the B-Field),

take the conversion factor from the graph on page 14 or from the table at the

measurement frequency and add it to the signal level in dB(µV) indicated by the

EMI meter. The result of this addition is the B Field strength in dB(pT).

E

XAMPLE

If the EMI meter is a 50-ohm instrument calibrated in dBm, add 107 to the

indicated signal level in dBm to convert it to dB(µV). Subtract 2 dB from result to

obtain magnetic field strength H in dB(µA/m).
