The electromagnetic (EM) clamp is a high efficiency broadband clamp-on injection device developed to test the immunity of electronic equipment when the standard IEC 1000-4-6 CDN using the direct capacitive coupling technique is not possible nor appropriate. The EM clamp is often used to test unshielded multiple conductor cables.
Fischer Custom Communications, Inc. offers two EM Injection Clamps, model F-203I-23mm and F-203I-32mm. FCC EM Injection Clamps offer unique benefits compared to conventional EM Injection Clamps.
For conducted immunity testing from 150 kHz to 230 MHz the increased efficiency can save the user as much as 100% on required CW amplifier power. The F-203I family requires less than 10 watts to develop the 10 volt open circuit level in accord with IEC 1000-4-6. When an additional ferrite decoupling or ferrite tube is used in the test the F-203I family requires less than 36 watts to develop the 10 volt open circuit level.
