IX-B3G Isolated ECG/EMG/GSR Biopotential Recorder


The IX-B3G recording module allows recording of up to three channels of ECG, EMG or EEG as well as GSR (galvanic skin response). The recorder includes iWorx LabScribe Recording and Analysis Software and connects directly to a USB port on either a Macintosh or Windows computer. The module connects to the subject by snap-leads to pre-gelled AG/AgCl electrodes for recording biopentials and a finger electrode to record GSR.

Electrodermal activity (EDA), is the property of the human body that causes continuous variation in the electrical characteristics of the skin. Historically, EDA has also been known as skin conductance, galvanic skin response (GSR), electrodermal response (EDR), psychogalvanic reflex (PGR), skin conductance response (SCR), and skin conductance level (SCL).  Human extremities, including fingers, palms, and soles of feet display different bio-electrical phenomena. IX-B3G, is a GSR meter( or a skin conductance meter) which displays the change electrical conductance between two points over time.


Kinesiology is the study of human and nonhuman animal-body movements, performance, and function by applying the sciences of biomechanics, anatomy, physiology, psychology, and neuroscience. When studying kinesiology,  surface electromyography  (sEMG or Surface EMG) is the measurement of choice.  The IX-B3G enables upto 3 channels of EMG recordings.


ECG signals can be measured with the IX-B3G.  Measuring 2 channels of ECG, Lead I and Lead II allows LabScribe to calculate Lead III, aVR, aVF and aVL .


In addition to measuring Bio-Potentials, each channel is also capable of measuring temperature using the TM-BIO temperature sensor.

Event Marker:

In addition to measuring Bio-Potentials, the Bio-channel is also capable of marking events using the EM-BIO Event Marker.

iWorx LabScribe ECG Software Module is a powerful and user-friendly tool intended to automate the analysis of ECG data from a variety of species. Specific analysis templates are included to accurately delineate PQRST onset, durations and amplitudes. Custom templates can also be created based on unique ECG profiles and saved to a library for future use. Other features include beat averaging, beat classification and outlier removal based on abnormal R-R intervals, heart rate, noise and activity, Pointcaré plots and scattergrams and the ability easily extract source data and average data as images or text files.The LabScribe ECG Software Module includes a comprehensive list of 24 calculations including R-R, PR, QT, QR and QTc intervals, QRS, T, P and TP durations, P, Q, R, S, T amplitudes and ST elevation. The software module is plug and play compatible with all iWorx data acquisition and analysis systems. A separate ASCII Text Import Module is also available that enables import of ECG data in text format that was recorded by any other acquisition program.

Heart Rate Variability  

Kubios HRV - Heart Rate Variability Analysis Software is an advanced tool for studying the variability of heart beat intervals.  Data can be exported from LabScribe using the edf export option and then imported into Kubios HRV for analysis, as shown in this technote


The iWorx ASCII Import Module enables import of data in text format that was recorded in any other data acquisition program. The module also allows the researcher to use the analysis functions in LabScribe2 software on data they may previously recorded with another a different program.Detailed information about using the modules is in the LabScribe Manual
