Test Kit 

The ETS-Lindgren Model 6505 Loop Shielding Effectiveness Test Kit is a set of 
loop antennas that includes the following: 

 

Model 6507 Active Receiving Loop Antenna 

 

Model 6509 Passive Loop Antenna 

 

Battery Charger 

Measuring Magnetic Shielding Effectiveness 

1. 

Set the transmitting and receiving antennas apart at a distance equal 
to 24 inches plus the thickness of screen room. 

2. 

Set up equipment as shown in the diagram on page 39. 

3. 

Turn generator to on position. 

4. 

Disable RF output of generator. 

5. 

Turn amplifier to on position. 

6. 

Turn receiver to on position. 

7. 

Turn receiver loop power on, and verify light is on. 

8. 

Set desired frequency on generator. Set the same frequency on 
receiver. 

9. 

Set the attenuator at maximum (100–120 dB) attenuation. 

10. 

Enable RF output of the generator.
