XY-Plot
The X-Y Plot is used to scan and map, with the aid of the main probe, the radiated emissions from the EUT. The plot is carried out at a selected single frequency. 

The results are presented as a colour coded map which can clearly identify the emissions from individual components and tracks. 

  X-Y Plots can be saved as references which enable comparisons to be carried out throughout the frequency range before and after the application of remedial measures and modifications.  The saved reference can also be used as part of an auto test for production audit or quality control.

Plot at 10mm The 10 mm plot resolution is an extremely fast method of obtaining a plot.  It is designed to provide a quick overview of emissions.  It is also the recommended resolution for comparative and  production audit tests where a pass/fail answer is sufficient.  Typical test times for 100 x 100 mm board is 1.5 minutes.
Plot at 5mm The 5 mm plot offers four times the resolution of the 10 mm plot.  This plot resolution is suitable for comparative and production audit testing.  Due to the higher resolution it is the preferred option for initial investigations in development work.  Typical test time for 100 x 100 mm board is 2.4 minutes.
Plot at 2mm The 2 mm plot resolution provides a high resolution plot capable of identifying emission and immunity traces from individual components and tracks.  This plot resolution is ideal for development and problem solving applications.
Plot at 1mm The 1 mm resolution provides a high resolution plot capable of pinpointing emissions and immunity traces to individual pins and tracks.  It is a relatively slow plot ideally suited for the final stages of problem solving.
Plot at 10mm with zoom A zoom plot carries out a 1mm or 0.5 mm plot on selected areas of a plot previously carried out with any of the lower resolutions.  Once a scan has been completed the test area is selected by clicking and dragging the right mouse button to the desired area.                             
   
In addition to the plots shown above, the results can be viewed as a 3 dimensional image. The user can zoom, rotate and move the image to get the best picture of the emission pattern.

XY-Plots can be saved as references which enable comparisons to be carried out before and after the application of remedial measures and modifications. Plots can also be included in automatic tests for Production Audit.
