Disturbance analysis added to Agilent’s EMI receiver

April 04, 2014 // By Graham Prophet
Agilent Technologies has added disturbance analyser 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 characterise 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 customised reports.
