Wider coverage and faster sweeps for EMI test

October 17, 2013 // By Graham Prophet
Agilent has two new options for its MXE X-Series electromagnetic interference receiver: 44-GHz frequency range and time-domain scans, extending frequency range and increasing scan speed

When configured with 44-GHz frequency coverage, the MXE is a single instrument that meets the requirements for compliance testing according to standards such as MIL-STD-461F and FCC Part 15. The extended frequency range also applies to the MXE family’s diagnostic capabilities, which can be used to identify the sources of unwanted emissions. Time-domain scans significantly reduce the time needed to create a list of suspect emissions prior to final measurements. This capability is becoming widely used in the automotive industry.


Agilent says that this gives compliance engineers a cost-effective alternative for compliance testing and diagnostic measurements in the lab and on the bench. Three capabilities that are now included with every MXE are:

Monitor spectrum: This feature adds live-spectrum and meter displays that make it easier to characterise signals and identify the frequency of peak emissions prior to a final measurement.

Amplitude probability distribution: By adding APD, which will be included in the upcoming CISPR 11 standard, Agilent is making it possible for users to become familiar with APD measurements in advance of the standard, which is expected to be released in the summer of 2014.

Control for external line impedance stabilisation networks: This feature enables users to control switching functions in two commercially available LISN transducers. These are used in compliance measurements of conducted emissions according to commercial and military standards.
