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.
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 analyser modes. To enhance instrument longevity, upgradeable options include CPU, memory, disk drives and I/O ports.
