EM Eye - ESD Event Meter

Installation, Operation and Maintenance

June 2017

Description

The SCS EM Eye Meter is capable of providing 

measurements for many various parameters, which 

are determined by the type of sensor connected to the 

EM Eye Meter. Below are the three sensors that are 

available now:

•  ESD Events Detection

 –  The portable, easy-to-use 

EM Eye Meter serves as a measuring instrument for 

most ESD signals.  The EM Eye Meter measures 

the magnitude of ESD events.  This meter also 

estimates the events’ magnitude for CDM, HBM and 

MM models.

•  Electromagnetic Field Measurement

 – Enables 

the EM Eye Meter to be transformed into an EMF 

Meter, Power Density Meter and EIRP Meter.

•  RF Signal Sensor

 –  The EM Eye Meter measures 

the amplitude of an RF signal.

User Features

Modular Construction

The EM Eye Meter with the modular construction 

concept can expand to different applications. With the 

current design, it measures the magnitude of most ESD 

events when in one of its filter modes, electromagnetic 

fields (EMF), power density, effective isotropic ally 

radiated power and radio frequency (RF).

Made in the

United States of America

 USER GUIDE TB-9023

Touch Screen to Power ON

The EM Eye Meter is designed with a modern user 

interface. All buttons and controls are within the display 

itself. With its display and touch screen, it is easier for 

users to quickly navigate through the features that were 

built into the meter.

Speaker and Headphone Alarm Outputs

The EM Eye Meter, with a speaker and headphones, 

allows flexible means for audible indications, beeping 

or “warbling” like a radio. If one is in a noisy place, a 

headphone jack for optional headphones can be used 

for clearer audio.

Easy Data Logging to Memory Card

The EM Eye Meter supports data logging by using a 

microSD card and exports to an Excel spreadsheet. 

Having data at hand enables quick analysis. Solutions 

can be decided quickly and can be measured on the 

spot.
