Transducers that do not require power may use connnection cables to connect stand-alone equipment that terminates in, for intstance, BNC, phono, or Male RCA connections. Use Transducer Connector Interfaces (TCIs) to adapt…

AcqKnowledge performs all internal calculations to the accuracy defined by the IEEE format for double-precision floating point numbers and stores the results of those calculations in double-precision floating point format.…

The BIOPAC Hardware Application Program Interface (BHAPI) can be used if the hardware in question is an MP200, MP200, MP36R, MP36, or MP45. The BHAPI is a set of dynamically linked…

File size is limited by the restraints of the operating system and the available memory space on your hard drive or disk (depending to which you save the file). Software…

External Cleaning / Disinfecting Instructions For any BIOPAC Systems data acquisition, amplifier, or accessory module: To clean the surface of the module: wipe lightly with a dry, lint-free cloth, or…

The easiest way to remove a portion of your record is to highlight the undesired segment and select Edit > Clear. The section of the data on the selected channel…

VREF, excitation voltage and reference voltage refer to the same concept. This is the voltage the DA100C series amplifier provides for connected transducers that need to be powered. The excitation…

To record bipolar EEG, you will need an EEG amplifier for each pair of electrodes that you want to calculate the potential difference between. It is important to note that…

The terminology for electrical connections to human subjects is not universally agreed upon. “Ground” and “reference” are often used interchangeably. This is not a good practice as there are different…

If you are using a single MP100/MP200 system, the maximum number of EEG amplifiers you can have is 16.  If more channels are required, it is possible to link acquisitions from…

Reference corresponds to the VIN- connection on EEG amplifiers; on the MP3X, if using the SS1LA lead adapter, VIN- is on the lead adapter. Use each ear as a reference…

Taking a deep breath and then holding it increases intrathoracic pressure (pressure inside the chest cavity), which compresses veins returning blood to the heart causing a temporary decrease in venous return…
