The BSL MP30/35/36 unit has four isolated, human-safe universal biopotential/transducer amplifiers that are controlled by the BSLPRO software. When recording data, it is important to set the gain of the amplifier as high as possible without clipping it. If you are unsure what gain to use for your signal type, the OptimizeRanges feature will adjust the screen display so that you can see the incoming signal relative to the range of the A/D converter. The OptimizeRanges option is located from the Display menu, by right mouse clicking, and also as a toolbar icon . A green bar located at the right edge of the channel display identifies the vertical range.
If the signal is very small, relative to the display window, increase the gain so that the signal fills more of the channel display region. This will maximize the resolution of the signal relative to the input signal range of the A/D converter. The following screen shots show an ECG signal with the gain set to 1K, 5K, and 10K. By increasing the gain of the amplifier to 10K, the signal is using the full range of the A/D converter.
Note: The OptimizeRanges feature only works on analog input channels.
The following screen shows data with the default ECG gain setting (1K).
The following screen shows the data with the gain set to 5K.
The following screen shows the data with the gain set to 10K.
The gain is adjusted in the Setup channels > View change parameters dialog
High-performance mobile fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). These top of the line systems provide cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. Mobile subjects are comfortable and can respond naturally in real-world situations to take a test or perform mobile […]
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 […]
