Input box converter (standard with multi channel amplifier) The input box converter QI-122AK provides LAN connectivity so it is easy to expand your EEG system. It connects all
amplifiers to the EEG-1200 via standard CAT5 Ethernet cabling. QI-122AK provides 16 additional DC inputs (multi
channel amplifier only) and connection for photic stimulator.
Wireless input unit, “Air-EEG” WEE-1000K (option) Up to 64 channels EEG data can be sent to the EEG unit by wireless
transmission. Wireless reduces stress to the patients and lets physicians
monitor the EEG data while the patients are moving freely. All options
(including digital video) of the EEG-1200 are available with the wireless
input unit. Innovative roaming functions and an optional SpO2 probe that
can be connected directly to the telemetry unit makes it suitable for all
kind of EEG- and PSG recordings.

Data review during acquisition Comparison mode: The EEG Scope function lets you look back into
and review previous epochs of EEG while simultaneously monitoring
current EEG acquisition. One side of a split screen shows previous EEG
epochs and the other side shows the current EEG.
On-line frequency mapping The EEG data can be shown as a frequency map during acquisition, so
you can easily check the frequency distribution.
Review Easy to use software interface EEG-1200 software has an easy to operate graphical user interface
which can be adapted to user requirements. Standard settings provide
an intuitive software layout making it easy to learn even for beginners.
Individual configuration of the software layout allows adapting EEG-
1200 to every need:
flexible arrangement of menu bars
colouring of waveforms
individual montage settings
Review of EEG waveforms Waveforms can be displayed in a variety of methods.
40 individual montages with up to 250 traces
Pre-defined or individual high / low cut filters.
Manual or automatic paging forwards and backwards is the standard
way of reviewing EEG waveforms. Other ways are the event bar or
DSA trend graph to navigate to interesting parts of the EEG recording.
Several measurement tools help to go into details.
A part of the waveforms can be copied into the note waveform
window to compare them to the current waveforms.
DSA trend graphs Frequency components of EEG waveforms and the amplitudes of each frequency are displayed as a DSA (Density
Spectral Array) trend graph on the review screen and EEG Scope. The DSA lets you find epileptic seizures of a
specific EEG frequency band over a long period of time at a glance. Up to 8 trend graphs can be displayed, each
with its own settings in regards of the electrodes shown.

the EEG-1200 is used exceeds the applicable RF compliance level above, the EEG-1200 should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the EEG-1200.

Avoiding Electromagnetic Interference (Impedance Respiration)
Impedance respiration measurement is very sensitive and affected by electromagnetic interference. Technological
limitations do not allow immunity levels higher than 1 Vrms for conducted disturbances induced by RF fields.
Electromagnetic fields with conducted disturbances above 1 Vrms may cause measurement error. Do not use
electrically radiating equipment near the impedance respiration measurements.

The JE-921A that is connected to the EEG-1200
must be used only in a shielded location with a
minimum RF shielding effectiveness and, for each
cable that enters the shielded location, a
minimum RF filter attenuation of 31 dB over the
frequency range 80 MHz to 2.5 GHz. Refer to the
note below this table.

Interference may occur in the vicinity of
equipment marked with the following symbol:
NOTE 1: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and

NOTE 2: It is essential that the actual shielding effectiveness and filter attenuation of the shielded location be verified to
assure that they meet the minimum specification.
* Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength outside the shielded location in which the JE-921A that is connected to the
EEG-1200 is used exceeds 3 V/m, observe the JE-921A that is connected to the EEG-1200 to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as relocating the JE-921A that is
connected to the EEG-1200 or using the shielded location with a higher RF shielding effectiveness and filter attenuation.
NOTE
The JE-921A that is connected to the EEG-1200 should be used in a shielded location with an RF filter
attenuation of 31 dB over the frequency range 80 MHz to 2.5 GHz. If the JE-921A that is connected to the
EEG‑1200 is used outside shielded location, use it in a location where the measured field strength is less than
0.3 V/m. To measure shielding effectiveness, consult a service engineer.
