Changing the ESD Event Parameters
1.To reset the ESD counter to zero, press the joystick momentarily.
2.To change the ESD threshold, press the joystick longer until “ESD” is displayed. Move the joystick left or right to decrease or increase the threshold value. On this screen, a “REF” symbol appears on the top left corner.
3.To disable or enable CDM, move the joystick up or down to “on” or “off” CDM filter. A PEAK symbol appears on screen when the ESD filter is active.
4.To finalize the settings, push the joystick longer until the main ESD Event screen appears. A “MEM” symbol appears momentarily in this process.
Application note: Measuring ESD Events
Test the system by shaking the screw container just above the antenna. Observe the number display showing magnitudes of ESD events. It is now ready for ESD event detection. The factory default for static events is 80dBuV/m.
Application note: Measuring EMI Noise
EMI are spurious signals that are similar in nature to ESD signals. Like ESD, they are also unwanted. EMI can be monitored by switching the ESD filter to “OFF”. EMI sources could come from RF generating equipments like phone, motors, etc. The main display should not show the “PEAK” symbol.
