Type 7334-1 Magnetic Emission Loop

 

7334-1 Loop Antenna

RE01 and RE101 Magnetic Emission Tests
 

Data

 

Solar Catalog

DESCRIPTION

The Solar Type 7334-1 Loop Antenna has been
designed as a substitute for the AT-205/URM-6
antenna and is a replacement for Eaton Model
94607-1. It uses 36 turns of wire on a 5.25"
(13.3 cm) diameter form enclosed in an electrostatic
shield as described in paragraph 5.2.1 of
MIL-STD-461A.

The Type 7334-1 is equipped with an epoxy-glass
base plate which serves as a spacer to enable the
user to place the loop at exactly 7 cm from the
face of the item under test as required by test
procedure RE01 of MIL-STD-462.

APPLICATION
Connection to the loop is through a BNC connector which enables coaxial cabling to the EMI receiver. The loop is supplied with a correction factor graph showing the values in dB which must be added to the reading of a 50 ohm EMI meter to obtain answers in either dB/μV/m or dB/pT. The correction factor decreases as frequency increases from 30 Hz up to approximately 15 KHz, where the factor levels off and remains relatively constant up to 5 MHz.
The Type 7334-1 Loop Antenna is required by Test Method RE01 in Parts 2 through 6 of MIL-STD-461C and RE101 of MIL-STD-461D.These portions of the specification require magnetic field emission tests of cables, equipments, systems and sub-systems installed in, or used in, all phases of military vehicles, ships, submarines, aircraft (including helicopters), spacecraft, or ground-based operations.

TEST METHODS RE01 and RE101
The Type 7334-1 Loop Antenna is positioned 7 cm from the face of the equipment under test with the plane of the loop parallel to the equipment face. The best position to begin with is opposite or near a joint or seam.
The associated EMI meter is then scanned over the range 30 Hz to 100 KHz searching for emissions. At the frequencies where emissions are found, the loop antenna is moved about the surface seeking the strongest emission level.
When a strong signal is detected, the loop is oriented on its axis for a maximum reading. This procedure is repeated for all surfaces of the equipment under test. Although the specification is not clear on the point, it appears to indicate that all six sides (including the bottom) of an equipment must be tested in this manner.
When testing cables, the loop antenna is placed 7 cm from the cable with the plane of the loop parallel to the cable. The non-metallic base plate of the Type 7334-1 Loop Antenna provides a convenient means for establishing the correct 7 cm distance.

7429-1 Magnetic Loop Antenna

RS01 Magnetic Field Tests
 

 Data

DESCRIPTION
The loop antenna used for generating radiated magnetic fields is fully described in Figure 1A of MIL-STD-461A. It consists of ten turns of number 16 A.W.G. wire on an insulated form 4.72" (12 cm) in diameter. The winding is placed on the form in a position which allows the form to be used as a spacer to place the winding 5 cm from the face of the item under test as required by test method
RS01 of MIL-STD-462.
The Type 7429-1 Loop Antenna has been designed to the exact requirements of the specification. The loop winding is placed on a durable plastic form and is equipped with banana jack style terminals for connection to the test setup. The loop is not shielded.

APPLICATION
In a practical RS01 test setup, the loop antenna is supplied with the required current versus frequency by the Solar Model 6550-1 Power Sweep Generator. The current is measured with a voltmeter connected across the Solar Type 7144-1.0 Precision Resistor which is connected in series between the loop and the generator.

The A.C. current in the Type 7429-1 Loop Antenna to generate the magnetic field intensity required by test method RS01 at 5 cm from the loop winding is depicted on a graph supplied with the loop. The required current varies from a few microamperes to about 5 amperes as frequency is adjusted over the range 30Hz to 50 KHz.

10KHz to 3 MHz

10 Amps

Data

DESCRIPTION
This antenna was designed as a replacement for Eaton 94608-1. It is similar to Stoddart 91117-2, 30-inch diameter loop, supplied with AN/URM-6B and NM-10A
EMI receivers. In addition to operating as a receiving antenna, the Type 9130-1 Loop Antenna is capable of carrying ten amperes in test setups for generating magnetic fields.
Although the antenna it is replacing is circular (30 inches in diameter), the Type 9130-1 Loop Antenna is almost square, 28.5" x 29.75" with 6.31" radius at each corner (12.4 cm x 75.5 cm with 16 cm radius). This larger area results in an improved pickup factor. The loop is wound with larger wire than the original, so that it can carry more current in the transmitting mode. Fitted with Type N connector.

APPLICATION
As a receiving antenna the Type 9130-1 is more sensitive than the original 30-inch diameter loops. The graph below shows the comparison when connected to a receiver with 50 ohm input impedance. When used to generate magnetic fields, the Type 9130-1 Loop Antenna is capable of carrying up to ten amperes through its eleven turns, making 110-ampere turns. With one ampere flowing through the winding, the magnetic field generated is over 277.5 volts-per-meter at one meter distance from the plane of the loop and 12.6 volts-per-meter at three meters distance. With ten amperes flowing, the field intensity is 126 volts-per-meter at three meters distance

9230-1 Radiating Loop Antenna

MIL-STD-461D/RS101 Magnetic Field Tests

Data

DESCRIPTION
Test Method RS101 of MIL-STD-461D requires radiated magnetic fields over the frequency range 30 Hz to 100 KHz to determine the susceptibility or immunity of the equipment under test (EUT). Two loop antennas are required for compliance with the requirements. The radiating loop is 12 cm in diameter and the sensing loop (used for calibration) is 4 cm in diameter. The Type 9230-1 Radiating Loop has been designed so that the Type 9229-1 Loop Sensor can be attached at the required 5 cm distance.

APPLICATION
The test method requires calibration of the radiated energy at 1.0 KHz prior to the test. Calibration of the Type 9230-1 Radiating Loop is accomplished by coupling the Type 9229-1 Loop Sensor to it at a distance of 5 cm.

The arrangement is indicated in Fig. 1 on the next page. With a known current flowing in the radiating loop, the magnetic field can be measured. Two graphs are supplied with the loops to make life easier for the test engineer. Fig. 2 shows a typical correction factor curve for the Type 9229-1 Loop Sensor. Fig. 3 indicates the amount of current flowing through the Type 9230-1 Radiating Loop to generate the required magnetic field, in dB/pT.

The current level to produce 110 dB/pT at 1.0 KHz is 3.0 mA. An accurately calibrated EMI meter or spectrum analyzer will measure this as 42 dB/μV. Adding the correction factor of 68 dB/pT/μV from Fig. 2 equals 110 dB/pT as required by the specification.
