National Instruments SCXI -1125 用户手册

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

All software-configurable settings are not configurable both ways. This section only 

discusses settings in MAX. Refer to Chapter 4, 

, for information on 

using 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, 

, for more 

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.

Refer to Chapter 4, 

, for information on configuring the settings 

for your application using Traditional NI-DAQ (Legacy).
