Electricity is an alternating wave that can sometimes interfere with electrophysiological recordings.
Diagnosys has created a feature to adjust for this noise called 50/60 Hz filter or Line filter.
The feature may be turned on per test or set as a default.
To turn on the filter within a test:
Click on Channels in the top row to open the Channels tab of the pop-out menu.
Turn ON the 50/60 Hz Line Filter.
In a Multifocal ERG Test Window:
See the side menu and toggle the 50/60Hz Line Filter box.
To default the 50/60 Hz filter to be ON:
Begin on the START page of the software.
Click on Configure System.
Open Test Method folder.
Find the test in question: ERG Test, VEP Test, etc.
Scroll to find Line Filter (ERG, VEP, EOG) or Runtime Mains Rejection (MF ERG),
Click to make a Green Check.
