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 AWG 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.

Solar feed-thru capacitorsare highly reliable and ruggedly constructed units for general use in screen rooms and other environments. The metal case with four husky threaded inserts lends itself to convenient installation with minimal effort. The threaded feed-thru stud will accommodate power current of the listed rating without heating or voltage loss. indicates available current and voltage ratings of the variousSolar 10 µF Feed-Thru Capacitors. All have low dissipation factors, high temperature ratings, high insulation resistance, doubly rated dielectric strength, and long life characteristics. To satisfy safety requirements, a bleeder resistor is included within the capacitors, which serves to discharge the capacitors when applied voltage is removed.

There are those who disagree with the RF conducted susceptibility test setup of Method CS02 of MIL-STD-462. Homemade rigs have sprouted to comply with the coupling capacitor requirement, each with its own disadvantage. Our littleSolar Type 7415-3 RF Coupleris the answer. A neat little box with BNC connectors and a pair of binding posts, it is rated at 270 VAC at the LINE terminals and 20 V RMS into the GEN port. It looks good and does a fine job.

Solar Type 9133-1 Three Phase Capacitor Assembly for Line-to-Line Capacitance in Delta Connected Power Systems. This handy device contains three capacitors, 10 µF each, connected to provide capacitance from phase A to B, A to C, and B to C. The capacitors are rated at 270 VAC. As a safety feature, each capacitor is paralleled with a 500 K resistor to prevent a voltage charge from remaining on the assembly after power is disconnected. It is fitted with 1/4-28 feedthru studs to facilitate making connection from three phase power to a three phase load up to 100 A. The Type 6512-106R capacitor can be used for the neutral in `wye` connected power systems.

Direct connection to the conductor carrying EMI current is not necessary, since the probe may be opened for insertion of the conductor into the window of the toroid and then closed again to form a toroidal transformer with the conductor acting as a one-turn primary.A correction factor graph is provided to convert measured µV to EMI µAs. When the EMI current is measured in dB above 1 µV as indicated on a conventional EMI meter,the correction factor will convert the measurement to dB above 1 µA.The correction factor is the inverse of the transfer impedance, Zt. Each probe is shipped with a graph of the correction factor versus frequency, keyed to the serial number on the probe.Under certain conditions, a current probe can be used to inject low level RF signals into individual wires or cable bundles. Ask our engineers for advice in the use of current probes for this purpose. Some current probes can be easily damaged or are otherwise unsuitable for this application.

The unique winding arrangement of this impedance matching probe* provides step-up or step-down ratios with respect to either: 1) the source impedance of the connected generator, when used for injection, or 2) the load impedance of the connected receiver, when used for reception. This results in maximum power transfer into or out of the transformer winding formed by the cable bundle passing through the window.
