EMI Measurement Application
Pre-compliant EMC emission test solution
RIGOL’s EMI Measurement Application provides a complete EMI pre-compliance solution with scans, peak tests, limits, and multiple simultaneous CISPR detectors. With the EMI Measurement Mode engineers can compare, analyze, and report on EMI issues throughout their design process. The EMI Measurement Application can be added to any RSAxxxN series Real-Time Spectrum Analyzer/VNA.
|This step by step guide explores using RIGOL’s EMI Measurement Application throughout the Pre-Compliance test process including:
Radiated Test Setup with a TEM Cell
A TEM Cell is a great option for some Pre-Compliance tests where Near Field Probes don’t provide enough repeatable data, but a full chamber is unnecessary or cost prohibitive.
Take a look at the test setup we will use for our step by step guide through EMI measurements
Configuring Traces & Detectors
An important first step for Pre-Compliance is selecting the detectors to start with. Different detectors may limit your sweep speed and change the meaning of the results. Learn how to set up detectors and traces.
In EMI mode select from these CISPR detectors:
Built-in scan table with independent settings for each range make it easy to configure complex scans with multiple detectors all on one screen
Analyze data from a completed scan against limit lines and search for peaks. Isolate these signals for further examination automatically.
Move between signals in the easy to use search results table.
Limit Lines and Margins
Access the built in limit lines or configure your own for custom testing. Use the limits and margins when searching for signals of interest or for interactive measurements using multiple detectors.
EMI Mode shows live measurements of markers or signals against multiple detectors simultaneously simplifying comparison and analysis.
Pre-Compliance testing is about more than just recording emissions. Use the EMI Application to compare between board revisions making sure the product is getting close to compliance as it gets closer to launch.
Make EMI measurements simpler and faster by automating the process. Combine scans, searches, and interactive measurements. Also conduct further analysis on signals of interest with a single button on the same instrument engineers use for advanced debugging of emissions and signals.
Saving and Using Test Setups
Relative measurements are critical in EMI:
Learn how to create, organize, and open complete test setups for comparison and data recording. Setups can include data traces and instrument configuration details.
Once the testing and debugging is complete, use the EMI Measurement Application to generate complete test reports with notes, screenshots, and data.
Integrate test, debug, and reporting all on one platform for consistency and productivity.
Watch the EMI Mode create html and pdf reports for the test archive.
Susceptibility testing with a Signal Source and a TEM Cell
TEM Cells can also be used in susceptibility or immunity testing. Functional testing during emissions is a simple validation step. Here is an example using the DSG800 signal source and the MSO7000 Oscilloscope
