EMC receivers and EMI analyzers are utilized for radiated and conducted emissions testing. These are essential pieces of equipment for when transient signals or spurious emissions are present, as they are used to collect and analyze data. CISPR, IEC, FCC, and MIL-STD have all established standards for testing emissions and suggest the use of an EMI receiver to be fully compliant. This is because EMI receivers are more reliable in making measurements. While testing, it is important to examine test standard requirements for Quasi-peak (QP) detectors or CISPR average detectors, requirements for resolution bandwidth (RBW) in regards to a satisfactory amount of measurement points per frequency span, noise floor extension, and software for pass-fail conditions that are not handled well by most spectrum analyzers. EMC receivers and EMI analyzers work best for pre-compliance testing, evaluating, and troubleshooting.
Avalon Test Equipment carries a variety of EMC receivers and EMI analyzers from top manufacturers (R&S, Keysight, and more) to meet your testing requirements.
Each R&S® ESIB combines the high sensitivity, large dynamic range and selectivity of a high-end EMI test receiver with the flexibility and speed of a top-class spectrum analyzer. The R&S® ESIB EMI test receivers fully comply with the basic standard CISPR 16-1-1 and carry out measurements in conformance with all civil and military EMI standards such as CISPR, EN, VDE, ANSI, FCC, BS, ETS, VCCI, MIL-STD, VG, DEF-STAN, etc.
The R&S ESR7 EMI Test Receiver is a dual instrument that measures electromagnetic disturbances while simultaneously functioning as a fully featured, powerful signal and spectrum analyzer for lab applications
The Rohde & Schwarz, Inc. FSP-38 spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Rohde & Schwarz, Inc. FSP-38. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Early evaluation of your design's EMI performance is essential for a successful product. The Keysight E7402A EMC Spectrum Analyzer is part of the E7400A Series which provides the capabilities you need in an analyzer to make in-house EMI pre-compliance testing a reality.
The Rohde & Schwarz ESIB family of EMI test receivers combines the high sensitivity, large dynamic range, and selectivity of a high-end test receiver with the flexibility and speed of a top-class spectrum analyzer in one instrument.
