The Keysight 8546A is a high-performance test receiver especially designed for making commercial EMI (Electro-Magnetic Interference) measurements. It fully conforms to the receiver standards described in CISPR (Comiteé International Spécial Des Perturbations Radioélectriques) Publication 16, C.I.S.P.R. Specification for Radio Interference Measuring Apparatus and Measurement Methods. This type of receiver is used for making measurements according to various governmental standards, such as FCC (U.S.A.), EN (Europe), and VCCI (Japan) regulations. The 8546A tunes from 9 kHz to 6.5 GHz, making it suitable for testing a wide variety of products ranging from ITE (Information Technology Equipment) and ISM (Industrial, Scienti c, and Medical Equipment), to household appliances and telecommunications equipment.
The 8546A consists of two parts—the receiver RF section and the RF filter section. The two units are connected together via several cables on the front and rear panels to form a single instrument. All control for both units is handled by the receiver RF section, whether manually from the front panel or automatically through the interface bus.
For precompliance and diagnostic EMI applications which do not require a fully compliant CISPR Publication 16 receiver, the receiver RF section can be used as a stand-alone instrument. The receiver RF section has the EMI-specific functionality to perform these types of measurements. The receiver RF section can be upgraded to an EMI receiver by adding a RF filter section and sending the pair to an authorized Keysight service center for calibration verification.
