EM Eye Meter —
ESD Event, Electromagnetic Field
and RF Signal Measurements
The Power of a Benchtop Meter in Your Pocket
Whether you are in charge of product development, EMC compliance or ESD
prevention, equipment installation and maintenance, or if you are involved in
research, your work depends on the test equipment you have available. What you can
or cannot achieve depends on the ability to take various measurements, to collect
and store data, to present the data in the most convenient way, and to process it on a
computer, along with the portability of your instruments.
To make your job a little easier, 3M has developed the EM Eye Meter – one of the
smallest and most versatile instruments for measuring EM fields, RF signals and
ESD events determined by the sensor connected to the EM Eye Meter. This meter
allows you to expand your instrumentation at a lower cost since adding a sensor is
less expensive than purchasing a completely new instrument. Weighing just 9 3/4
ounces, the EM Eye Meter can literally fit in the palm of your hand or in your shirt
pocket. The touch screen and color display make this instrument very easy to use.
ESD Events Detection
– The EM Eye Meter is capable of detecting ESD events and
characterize them in most HBM, CDM and MM models. It is capable of rejecting
non-ESD related events, making analysis easier. The meter is easy to operate and
can be used by almost anyone who is involved with ESD. It provides information on
estimated discharge voltages at a specific location, what time it occurred, and how
many discharges have occurred. The meter’s small size allows it to be used in tight
locations inside the tools or in a wider area of interest. For extended temperature
environments, the EM Eye Meter uses an optional remote antenna which will work
under most conditions. All information is recorded on an SD
™
card for easy review
and retrieval of data.
Electromagnetic Field (EMF) Measurement
– By simply placing the EMF sensor
head into the EM Eye Meter base, the EM Eye Meter transforms into a dedicated
EMF meter, a power density meter and an EIRP meter. The EM Eye Meter detects
and measures high frequency electric fields that may be present in equipment, tools,
circuit boards or on any process in a manufacturing area. The EM Eye Meter also
measures high frequency electric fields from mobile phones, over-the-air TV signals,
wireless LANs and any other source generating fields within its specification. The
EM Eye Meter comes with a miniature directional antenna that measures just one
parameter. The meter then can calculate several parameters from that original one.
The directional antenna reduces the influence of ambient electromagnetic fields
when measuring emission coming from the specific source. So whether you’re
in the fields of product design, mobile phones, TV signals or wireless LAN, the
portable EM Eye Meter is a helpful and important part of your toolbox.
RF Signal Sensor
– The EM Eye Meter, with the replacement RF sensor head, is
capable of measuring RF signals. Usually used by radio communications designers
and engineers, the EM Eye Meter will be able to provide a readout of RF signal
voltages. The EM Eye Meter offers exceptional sensitivity and linearity.

EM Eye Meter User Features
Modular Construction
The 3M EM Eye Meter with the modular construction concept can expand to different applications.
With the current design, it measures ESD events, electromagnetic fields (EMF), power density,
effective isotropically radiated power and radio frequency (RF).
™
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 head-
phones can be used for clearer audio.
Remote or Local Antenna Selection
3M recognizes that an engineer may be working in tight physical locations. The EM Eye Meter is
small and portable with expansion accessories that can be fitted in hard-to-reach places, and in hot
or cold temperatures.
Easy Data Logging to Memory Card
The EM Eye Meter supports data logging by using a miniSD
™
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.
