Page 9: Understanding The Terminology
Cameras A high resolution USB camera is attached to the robot and used to take pictures of the DUT. The detected electromagnetic emission intensity is color coded and then superimposed on the picture taken by the USB camera prior to the test. RF Amplifier In cases where signals are too weak to be detected directly by the spectrum analyzer, an external RF amplifier may be required.

Figure 5:SmartScan window after a "Project" (ESD-1) has been created. 4.2. Calibrate Probe Z Offset Most probes from API have same length, however, slight length variation may occur due to the probe assembly or probe mounting. Since it is important to know the actual scan distance (height) between the probe tip and the DUT surface, the software has to know where the probe tip is relative to the predefined origin.
Page 13: Figure 6: Probe Z Offset Example
offset calibration is the procedure to give the slight variation to the software. An example of probe Z offset is shown in Figure 6. Figure 6: Probe Z offset example. a. Double click on "Probe Settings" under project name on left pane, and select "Z wizard" after the "Probe Settings"...
