It is possible to validate the signals coming from any BIOPAC biopotential amplifier* by using a CBLCALC 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 CBLCALC is connected to. The CBLCALC 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 from the source signal level, contact BIOPAC for further assistance.
In this online webinar, Frazer Findlay, CEO of BIOPAC, will explain how to set up a Facial EMG study and record great Facial EMG data using the newest Smart Amplifiers. He will demonstrate where to place the electrodes and best practices for recording signals from the muscles tied to our emotions. Join us Thursday, April 25th 8:00 AM to 9:00 PM PT
Recent Studies using BIOPACs MP-Series (MP160, MP150) data recorders, ECG Amplifiers, and BioNomadix Wireless recorders: Singing style to infants Mothers around the world sing to infants, presumably to regulate their mood and arousal. Lullabies and playsongs differ stylistically and have distinctive goals. Mothers sing lullabies to soothe and calm infants, and playsongs to engage and […]
Alex Dimov, BIOPAC Sales Executive, was interviewed at the Neuromarketing World Forum by Inside Marketing to discuss how virtual reality can improve marketing research. Alex explains how VR can be used to present virtual iterations of a product to save time and money, and notes that measuring physiological responses adds lots of information for product and messaging […]
