Power source The Nicolet EEGwireless32/64 amplifier can derive its power from either an AC
outlet through the medical grade power supply, from one or two external battery
packs, or in the case of a fixed installation, wallplate power.
The Nicolet EEGwireless32/64 amplifier has a second power port, which allows the
addition of a second battery pack for longer recording time or a medical grade power
supply. If the medical grade power supply is plugged in while a battery is also
plugged in, the battery pack will charge.
There is an internal battery in the Nicolet EEGwireless32/64 amplifier that allows
switching the external battery pack while in the middle of a study. When the external
battery pack requires changing, it can be removed without interfering with the study
as long as it is replaced within 10 minutes of removal.
If an external battery or AC power is connected to the Nicolet EEGwireless32/64
amplifier, the internal battery will be charged.
Communication EEG data can be transmitted to the Nicolet acquisition system either by an Ethernet
cable or wirelessly using a recommended 802.11 b/g access point. The Nicolet
EEGwireless32/64 amplifier is IP addressable and can connect directly to a hospital
network or private LAN.
Memory card The Nicolet EEGwireless32/64 amplifier also provides onboard storage of EEG. The
Nicolet EEGwireless32/64 amplifier has an onboard memory card used to record
data. When the memory card reaches within 10 minutes of its capacity, the Nicolet
EEGwireless32/64 amplifier produces an audible alert.
Sampling rate The Nicolet EEGwireless32/64 amplifier provides selectable sampling rates from 128
Hz - 12000 Hz.
When operating at 12 kHz Sample Rate, ensure the electrode lead cover is connected.
Also, do not wrap the Nicolet EEGwireless32/64 amplifier in a blanket or place under
a pillow.
