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
Eyes are the window to the soul and, more importantly, the brain. Psychophysiology, neuroscience, and consumer neuroscience researchers use eye tracking technology to understand emotion, behavior, subject response, decision-making, and human performance—and to help improve products and services. But not everyone knows where to start or how and why to use this important technology. A panel of eye tracking experts will present typical use cases and the latest eye tracking technology.
Watch this on-demand presentation with Q&A to learn the fundamentals of eye tracking!
Solving Physical Stress Issues for Surgeons Physical stress in the operating room is common for surgeons, considering how much time they spend in an upright standing position during surgical procedures. With procedures that require standing for several hours and average reported working times of 60-80 hours a week, surgeons seem to be at risk for musculoskeletal […]
