4.0 Operation

Before connecting any components, follow the

safety information in the ETS-Lindgren

Product Information Bulletin included with your

shipment.

The reception pattern of the Model 7604 Magnetic Field Pickup Coil is directional,

having a shape essentially of a dipole. Maximum pickup of alternating magnetic

field occurs when the field vector is aligned with the coil axis.

1.

Connect the Model 7604 to the input connector of an EMI meter using

a coaxial cable fitted with a BNC plug. The EMI meter may have an

input impedance that is either high (500 ohms or greater) or 50 ohms.

2.

Make the measurements of the Equipment Under Test (EUT) in

accordance with the applicable standard using the appropriate

measurement method; for example, MlL-STD-462 [2], Method RE01.

Methods of measurement may be found in [2] and [3], and further

information on the measurements and a discussion of how to make

them may be found in [5].

3.

Reduce the data to flux density by applying the conversion factor at

each frequency where an emission from the EUT is found. The

conversion factors for the Model 7604 are illustrated in the graph on

page 14; these factors are also tabulated in the table on page 16. They

are provided in decibels referenced to one picotesla

per microvolt: dB(pT/µV).
