In Traditional NI-DAQ (Legacy), you can configure software settings, such 
as configuration, voltage excitation level, filter bandwidth, gain/input 
signal range, and calibration settings in the following three ways:

•

module property pages in MAX

•

virtual channels properties in MAX

•

functions in your ADE

All software-configurable settings are not configurable in all three ways. This 

section only discusses settings in MAX. Refer to Chapter 4, 

information on using functions in your application.

Most of these settings are available in module properties and/or using 
virtual channels:

•

Filter bandwidth—configure only using module properties. You also 
can set bandwidth through your application. The default filter 
bandwidth level for Traditional NI-DAQ (Legacy) is 4 Hz.
