Streaming The Signal With 500 Hz Sampling Frequency And With The Measure Impedance On Ref Box Selected - MBT SMARTING 24 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).
