Agilent Technologies Introduces EMI Receiver that Enhances Compliance Testing through Excellent Input Sensitivity
Agilent Technologies Inc. (NYSE: A) announced the introduction of the N9038A MXE EMI receiver, which is designed for laboratories that perform compliance testing of electrical and electronic products. The MXE enhances electromagnetic interference (EMI) measurement accuracy and repeatability with a displayed average noise level (DANL) of -163 dBm at 1 GHz. This represents excellent input sensitivity, an essential receiver attribute that reduces the effects of electrical noise.
The MXE is fully compliant with CISPR 16-1-1 2010, the International Electrotechnical Commission recommendation that covers measurement receivers used to test conducted and radiated electromagnetic compatibility (EMC) of electrical and electronic devices. With outstanding measurement accuracy of ±0.78 dB, the MXE exceeds CISPR 16-1-1 2010 requirements.
The built-in suite of diagnostic tools, including meters, signal and measurement lists, markers, span zoom, zone span and spectrogram displays, make it easy to monitor and investigate problem signals. The MXE is also an X-Series signal analyzer capable of running a variety of measurement applications such as phase noise. By enhancing the analysis of noncompliant emissions, these capabilities enable EMI test engineers and consultants to evaluate signal details and deliver new insights about the products they test.
"With the ability to move seamlessly between EMI-receiver and signal-analyzer modes, the MXE is a single tool that can help test labs expand their service offerings beyond compliance testing," said Guy Séné, vice president and general manager of Agilent's Microwave and Communications Division. "As an easily upgradeable X-Series signal analyzer, the MXE can keep pace with evolving standards and requirements."
Agilent's X-Series is an evolutionary approach to signal analysis that spans instruments, measurements and software. It provides the flexibility to address business and technical requirements across multiple products and programs. The X-Series also provides a consistent framework for signal analysis, enabling teams and their projects to move at a faster pace. In addition to the new MXE EMI receiver, the X-Series includes the high-end PXA, midrange MXA, economy-class EXA and low-cost CXA, as well as more than 25 industry-leading measurement applications.
EMI and the Importance of Testing
EMI is a disturbance that can affect the proper operation of electrical and electronic circuits through emissions transmitted over the air (radiated) or through the AC line (conducted). EMI testing checks products for unwanted emissions that can affect other devices.
Compliance testing is an important step in product development because EMC is regulated by the governments of most countries. Full compliance testing by an accredited lab is typically costly, and failing means a complete restart of the testing process. As a result, many manufacturers are performing precompliance testing with a CISPR-compliant receiver to increase the likelihood of passing compliance testing on the first try.
