Immunity measurement

 part4
 
 
 
  Visual Immunity test   The measuring procedure  
  The patented Immunity software option allows you to use a Detectus EMC-Scanner system, a signal generator with a small antenna and an Error Detection Device to measure the immunity against radiated electro magnetic interference of components, cables, PCB’s and products. The measurements are easily interpreted and can be repeated for objective comparison.
 part4 During measurement the EMC-scanner moves the antenna to predetermined measuring positions above the test object. In each measuring position the signal generator sweeps in frequency and amplitude while the EDD measures for test object failure. If your signal generator allows it, you can also use different modulations such as FM, AM and Pulse.  
         
  Use any Error detection device   Measurements and reports  
 

The Error Detection Device, or EDD for short, can be any type of GPIB or VISA controllable instrument that measures a value from the test object to determine when the test object fails. The EDD can for example be a voltmeter or a protocol tester.

 part4 From an Immunity Scan measurement the DSS software can produce two or three dimensional colour maps showing sensitive hot spots at any frequency. Also printable reports can be generated. The reports include the colour map, graphs and all the measurement settings.
