Discontinuous Disturbance Measurements with EMI Receiver

02 June 2014 – Agilent announced the addition of disturbance analyzer capabilities as a standard feature of its N9038A MXE EMI receiver. For those who need to make discontinuous-disturbance, or click, measurements, the MXE simplifies and automates data collection, analysis and report generation in accordance with CISPR standards 14-1 (emissions) and 16-1-1 (measurement apparatus and methods).

A wide range of commercial electronic devices, such as washing machines, refrigerators and thermostats, generate discontinuous conducted emissions. In the MXE, click measurements are made simply and quickly using auto-coupled settings that link the chosen measurement frequencies to the proper instrument configuration and relevant CISPR test limits. Test duration can be set as desired, up to two hours. The user can also configure the measurement to end after a specific number of clicks have been detected.

Clearly displayed results help test engineers easily characterize the conducted-emissions performance of the device under test and evaluate it against regulatory requirements. Intermediate results are displayed as data is collected, enabling the user to track the measurement process. Upon completion, final analysis is automatically generated, showing pass/fail results, a list of all crucial parameters (e.g., click count, click rate, etc.) and the status of any applied exemptions. Results can be documented with standard or customized reports.

“With the addition of click measurements, the MXE continues to keep pace with the regulatory requirements that define the demands on engineers who perform EMC testing,” said Jim Curran, marketing manager of Agilent’s Microwave and Communications Division. “For these engineers, success depends on tools that enable them to do more in less time, today and tomorrow, which is our ongoing vision for the MXE.”

N9038A MXE EMI Receiver

The MXE is a standards-compliant EMI receiver and diagnostic signal analyzer built on an upgradeable platform. It meets commercial (CISPR 16-1-1:2010) and military requirements (MIL-STD-461).

To help users diagnose noncompliant signals, the MXE includes a variety of built-in tools, such as diagnostic resolution bandwidths, a range of detectors, multi-trace displays, marker functions, trace zoom, zone span, spectrograms and Agilent-exclusive Strip Chart. To speed the evaluation of signal details, the MXE enables seamless transitions between its EMI receiver, monitor spectrum and spectrum analyzer modes. To enhance instrument longevity, upgradeable options include CPU, memory, disk drives and I/O ports.
