EMI receivers are high performance instrumentation that acquire data for analysis. EMI receivers are used for scenarios where transient signals or spurious emissions may appear and must be acquired with fast acquisition rates. Multiple organizations have set standards for testing these emissions, including
CISPR,
IEC/
EN,
FCC, and
MIL-STD, whom recommend using a EMI test receiver for fully compliant testing.
For making these measurements successfully, EMI receivers are more reliable than
spectrum analyzers. Many considerations should be made including the following: Resolution bandwidth (RBW) requirements for taking a sufficient amount of measurement points within a frequency span. Requirements for Quasi peak (QP) detectors or CISPR average detectors called out by test standards. Other important requirements include filters, low noise floor, and software displaying pass or fail conditions according to certain test standards. Consider the use of solely a spectrum analyzer when testing before full compliance is required.
Advanced Test Equipment Corp. provides the highest performance and widest selection of EMI test receivers and EMC analyzers ranging for 2Hz to 44GHz. All units are stocked with ISO 17025 calibration to provide the most accurate measurements for
CISPR,
IEC/
EN,
FCC, and
MIL-STD tests. Calibration certificates are provided with the rental and all calibrations are performed at our onsite A2LA accredited lab.
