EMI X-Series Measurement App, Traditional UI  

N6141EM0D  

Technical Overview

– Measure emissions with built-in commercial–and MIL-STD–compliant bandwidths, detectors, and band presets

– Compare measured emissions to regulatory limits

– Continuously monitor signals with bar meters to detect maximum amplitude

– Collect lists of suspect emissions

– Differentiate between ambient signals and device emissions

– View signals over time to identify intermittent responses

– Generate reports in HTML format including signal list, images and trace, and correction data

– Flexible licensing provides the option of using perpetual or time based licenses with one or multiple signal analyzers

EMI Measurement Application  

To avoid costly delays that can result from failed compliance testing, Keysight’s EMI measurement application on X-Series signal analyzers allows you to perform precompliance measurements and diagnostic evaluation of your designs. Find and fix problems before they enter the test chamber with the N6141EM0D measurement application.  

The application’s wide range of features enables you to:  

– Use the scan table to set up frequency ranges, gains, bandwidths, and dwell time

– Scan a frequency range and display the results in log or linear format

– Identify suspect signals in the frequency scan

– Measure the peak, quasi-peak, EMI-average or RMS-average values of these suspect signals and place the results in the signal list

– Easily identify signals that fail the regulatory agency limit

EMI precompliance measurements  

Performing precompliance radiated and conducted emissions measurements early in the design cycle can reduce development expense by ensuring new designs will pass final compliance testing at an accredited facility, avoiding costly redesign and re-testing. For a step-by-step guide on how to make precompliance measurements according to regulatory agency limits, refer to the application note, Making Conducted and Radiated Emissions Measurements, literature number 5990-6152EN.  

Conducted emissions measurements  

The EMI measurement application allows you to measure the emissions that are conducted along a power line. The transducer used to couple the emissions of the power line to the signal analyzer is a line impedance stabilization network (LISN). The frequency range of conducted emissions is 9 kHz to 30 MHz, depending on the regulatory agency.  

Radiated emissions measurements  

Performing precompliance radiated emissions measurements is not as straight forward as conducted emissions measurements. When measuring to commercial standards, the antenna is placed 3 to 10 meters from the device under test (DUT) and the DUT should be rotated in order to find the maximum radiation. With the addition of the EMI receiver measurement application, the X-Series signal analyzer becomes a powerful EMI precompliance measurement analyzer. Measure designs to the latest CISPR 16-1-1 or MIL-STD requirements. The robust signal list feature enables you to quickly differentiate between the DUT and the ambient signal environment.  

Regulatory standards  

X-Series signal analyzers with the EMI measurement application can be used for making precompliance measurements to any international EMC standard. Simply select the performance level and frequency range for your application.
