ECG/EOG/EMG biosignals recording

Fig 1. Montage creation All stanadrd Mitsar-EEG amplifiers have extra bipolar channels for extra biosignals recording. Following data can be acquired: Electrocardiogram (ECG or EKG)Electrooculogram (EOG)Electromiogram (EMG)RespirationAnd etc. Below is the scheme of electrodes placement of the subject body or face to record proper signal. It is also required to add POLY (BIO) channel to the montage like shown on the EEGStudio screen capture on Fig 1.Be aware that signal amplitude of EEG and biosignals could be different and it might be [...]

Amplifier functional test / Calibration signal.

To check the EEG amplifier performance you can use calibration (test) signal mode. In this mode the Mitsar-EEG switches EEG amplifiers inputs to the internal square wave generator 1,0 Hz frequency and 100uV amplitude. Data input from the sensors functionally differs from the calibration signal input only by the input signal source switching circuit. The obtained test signal should look as follows: Test procedure: Disconnect all sensors and electrodes from the Amplifier inputs.Choose monopolar montage with REF as a reference.Start calibration signal [...]
