SIGVIEW supports data acquisition of analog signals by using most National Instruments(R) data
acquisition devices (www.ni.com).
For general concepts and details regarding data acquisition in SIGVIEW, please see Data
acquisition overview. A standard NiDAQmx driver is used for data acquisition.
If you choose "NiDAQmx" as a device type, you will be able to set various device-specific options
in the following dialog:
First of all, you have to decide about the measurement type. It depends on your sensor type,
DAQ device type etc. Please consult your DAQ device manual for details. Each of supported
measurement types corresponds directly to one of low-level NiDAQmx driver functions. You can
visit a corresponding link below to find more information about parameters for each measurement
type directly on ni.com website:
"Voltage" measurement is a default measurement type and should work with most devices. Other
types of measurement will usually need special device types with excitation, IEPE option etc.
In case your device does not support requested parameters, you will get an error message
directly from the underlying NI driver. In that case, you will have to consult device manual and test
with different settings.
For example, all measurement types which use excitation are very restrictive regarding the input
range parameter. You have to take care that it fits a specified input range of your device in the
specific used mode.
