SMARTING User Manual

-
The electrodes on the brain sketch can display either the impedance
values on each electrode position, or the electrode name, which is
user specified option (7)
-
If the keyboard marker field (8) is checked, the keyboard stream will
become active and the keyboard presses can be visualized and
recorded in an XDF file.
-
When the
Test Signal
box is checked (9), SMARTING device starts
generating and streaming test square signals. This option can be used
to check if the device is streaming correctly without connecting the
cap and a measurement subject – if signals are appearing and there
are no lost data packages, the connection quality is verified;
-
To stream the gyroscope data together with the EEG data check the
Include gyro data
box (10);
-
To select the impedance values select the
Measure impedance
button (11). Otherwise, select the
No impedance measurement
button (13);
-
Selecting the
Measure impedance on Ref
box (12) allows measuring
impedances on the reference electrode (explained in subchapter 6.3
and in Figure 6.5);
-
The EEG data can be streamed with 500 Hz (14) or 250 Hz (15)
sampling frequency.
Note: If the data are streamed with 250Hz sampling frequency,
measuring the impedance values is not possible.
Upon setting up all the desired parameters, the EEG signal starts streaming
upon clicking the
start streaming signals
button (16) in the main window
(Figure 6.4).
