Artifact Rejection verification procedure

When data acquisition is configured to acquire using “Averaging”, some signal amplitude excursions may need to be excluded during the averaging process. Artifact Rejection, available via a checkbox in the averaging setup, is a feature for just this purpose. 

To perform on-line averaging, first choose “MP150 > Set Up Acquisition…” (older versions of AcqKnowledge) or “MP150 > Set Up Data Acquisition…” and choose “Length/Rate” in the pane on the left (AcqKnowledge version 4.4).  In the top row of pulldown menus, choose “Record” and “Save one” using “Averaging”.  Underneath “Averaging”, a “Setup” button will be enabled.  Click that button to set up various aspects of averaging (e.g., the number of trials) and click the “Artifact rejection” checkbox.

When artifact rejection is enabled this way, the MP150 System will ignore any trials that contain signals exceeding the artifact rejection thresholds, keep track of how many trials have been rejected, and add that number of trials to the total number of trials to be acquired. This allows users to “re-try” a trial that was rejected due to the presence of artifact.

The Artifact Rejection – Verification Procedure Artifact Rejection - Verification Procedure provides a procedure/test case to confirm that AcqKnowledge Artifact Rejection is functioning properly.
