System Frequency Domain Analysis: Mixer Data

This example demonstrates System Frequency Domain analysis of a behavioral MIXER element with mixer spurs data from a NMF file. The schematic and data file for the example are available in the Examples directory.

Open the project on the Examples directory.

  1. From the File menu, select Open Examples to open an explorer window.
  2. Open the Electronics Desktop directory, then Circuit, then RF_Microwave, the System directory, then select the file System_FD_Mixer_Data_Example.aedt. Click Open.
  3. The Examples directory is write-protected. Use File>Save As to save the example project to a directory where you have write permission. A Handle Project Directory Files window opens showing you the supporting model files that is copied along with the project. Click OK.
  4. The schematic opens in the design window:

  5. Select the MIXER component to display its properties. The mixer reads the mixer spurs data from a data file, NMFSpurTable.nmf (file property).
  6. Expand the Analysis folder, right-click and select Analyze (you may need to use Force Analysis).
  7. When the analysis is complete, expand the Results folder and click the spur_out report to see the spectral distribution of the mixer spurs output.
