The EMC Scanner measures the emission from components, cables, PCB’s and products. The system consists of an X-Y-Z robot, a spectrum analyzer with near field probes, possibly a GPIB adapter for communicating with the spectrum analyzer and a personal computer with custom software.
During measurement the robot moves the near field probe to predetermined measuring points above the test object. At each measuring point the location of the probe and the value of the emission intensity are stored in the computer. When the measurement is finished, the results can be documented in different types of reports.
