It is possible to validate the signals coming from any DA100A/B/ or C amplifier by using a CBLCAL* Calibration Cable. The cable connects to the front of the amplifier and the UIM100C Analog Output 0 or 1, or to a known signal source in the ± 10 V range. Create a stimulus signal using AcqKnowledge and monitor the output of the amplifier that the CBLCAL is connected to. The CBLCAL will attenuate the output signal (1/1,000), and the amplifier will amplify the signal by the gain setting.
For example, if the stimulus signal is 1 V and the gain setting is 1,000, the corresponding signal from the amplifier should be 1 V. The signal can be used for amplifier validation and signal calibration.
If the signal is significantly different than the source signal level, contact BIOPAC for further assistance.
* Note: Most other amplifiers require CBLCALC, not CBLCAL.
Day Passes T4: Tools, Trends, Techniques, and Technology Monday, July 24, 2017 – Wednesday, July 26, 2017 Join BIOPAC for hands-on, small-group human physiology workshops, presented by renowned experts, on the beautiful University of California at Santa Barbara campus in Santa Barbara, California, USA. Who should attend Anyone who records and analyzes human physiology data […]
The Mobita 32-Channel EEG recording system was used in research examining if physiological data can be used to predict truly random events that correspond to perceptual stimuli. Baumgart, et al. from the University of California Santa Barbara utilized a quantum random number generator (qRNG) to choose from three randomized conditions: light, sound, and no stimulus. […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies in monitoring respiration and cardiovascular activity. The coupling between peripheral microcirculation and slow breathing: The purpose of this study was to investigate the coupling of breathing movements and microcirculatory blood […]
