In NI-DAQmx, you can configure software settings such as filter
bandwidth and gain/input signal range in the following ways:
• Task or global channel in MAX
• Functions in your application
These sections describe settings that you can change in MAX and where
they are located.
• Filter bandwidth—configure the Device tab using either NI-DAQmx
Task or NI-DAQmx Global Channel. You also can set the value
through your application.
• Input signal range—configure the input signal range using either
NI-DAQmx Task or NI-DAQmx Global Channel. When you set the
minimum and maximum range of NI-DAQmx Task or NI-DAQmx
Global Channel, the driver selects the best gain for the measurement.
You also can set it through your application.
• Modes of operation—configure only using chassis installation in
software. Refer to Chapter 1,
information on chassis installation. The default setting in NI-DAQmx
is multiplexed.
• Terminal block attenuation—for terminal blocks with manually
adjustable attenuation such as the SCXI-1327, you must configure the
attenuator in the chassis configurator. Refer to the SCXI Quick Start
Guide for more information.
