  • Page 8: Limiting Electromagnetic Interference

    LIMITING ELECTROMAGNETIC INTERFERENCE (EMI) This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to Part 15(B) of the FCC Rules. These limits are designed to provide reasonable protection against a harmful interference in a residential installation.

  • Page 9: Switching Power Supplies & Rf Noise

    SWITCHING POWER SUPPLIES AND RF NOISE Switched mode power supplies ( SMPS ) employ high frequency switching and thus, are a source of radio interference, a recipient of radio interference and a conduit of radio interference. ( Older linear type trans- former based power supplies do not employ high frequency switching voltages and will be quieter as compared to switching type of supplies ).
  • Page 10 The receiver may “hear” the power supply. A slowly moving, slightly buzzing carrier heard in the receiver may be caused by the antenna being too close. As with the transmitter related noise pick up, a loose coaxial connector or a broken or a missing ground may aggravate this problem. Normally these noises will be below the background or “band”...
  • Page 11 Following additional guidelines may be followed to reduce the effects of RF noise: Use additional appropriate AC radio frequency interference (RFI) power line filter immediately before the ac input of the power supply. Recommended: Corcom Inc. ( www.cor.com ) “Q” series. Filtered, ferrite coated cord set (www.emceupen.com ) is another choice.
