This Biopac Student Lab 3.7.5 Lesson 2 script update sets a 60 Hz or 50 Hz Notch filter (based on the Line Frequency setting). The filter is currently set to 0 Hz, which may result in a very “noisy” signal under certain conditions because there is no filter to knock out induced interference from wall power.
To install this updated script:
Download (save) the “L02-EMG-2.zip” file to the desktop.
Extract and open the zipped folder.
Rename the “L02-EMG-2” file to remove the “.dat” extension.

Easily record great electrodermal activity (EDA, GSR) data. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level voltage connection to the data acquisition system and reduces noise artifact. AcqKnowledge Smart Amp setup includes guides and prompts to prevent […]
