Shown are six independent, and synchronized, MP200 systems collecting up to 16 channels each, monitored via remote central station. Extensible to thousands of channels. #dataacquisition #physiology #lifescience #extensible #remotemonitoring…

Channel contention must be considered when connecting the analog output sourcing from external devices to an MP1X0 Data Acquisition System. Considerations for MP200 or MP200 users follow; MP100 users should refer…

The Biopac Student Lab MP3X data acquisition unit uses adjustable hardware filters, fixed hardware filter, anti-aliasing filter, and adjustable digital filters. Filters are applied in the following sequence: Additional filtering…

The EOG100C amplifier can record from DC to 100 Hz and is designed to measure a signal correlated with the corneal-retinal potential (the small electrical potential difference between the cornea and…

The following issue exists on AcqKnowledge 3.9.x for Mac:   FIR Filter: Windowing selection reverts to Bartlett and then filters the data.

To interface a Gould transducer to BIOPAC hardware, you will need an interface cable from FOGG SYSTEM and a BIOPAC interface. Many BIOPAC interface options are supported. On the FOGG…

The Nerve Chamber can be connected to biopotential amplifiers and/or a stimulator. Biopotential amplifiers (MCE100C, ERS100C, or EMG100C) connect via three JUMP100 connectors and three CBL200 adapter cables or, for…

Sample rates for physiological signals acquired by the MP40 Biopac Science Lab system:   ECG 1000 EMG 1000 EOG 250 EEG 250 RESPIRATION 500  

In AcqKnowledge for Mac OS, the FIR Filter (Low Pass) transformation  is performed with Bartlett windowing regardless of the selection, which reduces the signal amplitude. Work-around: Use the IIR filter…

Calibration is performed prior to recording. It is assumed that the amplifier has no offset; see baseline offset if necessary. The gain of an amplifier  indicates the factor of amplification of…

To invert a waveform: Select “Transform > Waveform Math…”. Source 1 should be the channel to be inverted, the operation should be “*”, Source 2 should be K (constant), and the Destination should…

MODULATION OF QRS AMPLITUDE Several anatomical and physiological factors determine the amplitudes of the Q, R, and S waves in the ECG of a normal person. These factors include the…
