Specifications include, but are not limited to: This equipment assesses multiple physiological parameters simultaneously and yields highquality physiological data that allow for the examination of cardiovascular stress. BIOPAC MP160 has a 400 kHz aggregate sample rate for the data acquisition system, up to 100 kHz for any one channel, and the other products on the market do not offer this. The AcqKnowledge software has many automated analysis algorithms that work with the hardware and this software is proprietary to BIOPAC Software Engineers. This equipment includes cutting-edge systems with the ability to examine blood pressure, cardiac output, system vascular resistance, EMG and electrocardiogram (ECG) simultaneously. This equipment is the standard for social psychologists examining challenge and threat reactivity. There are no other companies that make the same equipment or distribute the same equipment as BIOPAC Systems, Inc. To this end, BIOPAC Systems, Inc. is used by the leading researchers in my field for the assessment of physiological indicators. In addition to being compatible with existing data being brought from our researcher’s prior institution and with a collaborator at the University of Maine, we must obtain this system as it is what was used to collect prior data on ongoing projects.
