The following example illustrates the difference between physical and virtual channels and demonstrates how to create virtual channels with the API. Problem Create an NI-DAQmx virtual channel to measure ...

Setting Pulse Train Polarity and the Initial Delay State - NI-DAQmx 18.6 Manual www.ni.com/documentation/en/ni-daqmx/18.6/mxcncpts/pulsetrainpolarity/
The idle state, which controls the pulse train polarity, is applied to the signal when a task transitions to the Committed state (which happens automatically when the task starts). The idle state polarity ...

Cold-Junction Compensation Channels - NI-DAQmx 18.6 Manual www.ni.com/documentation/en/ni-daqmx/18.6/mxcncpts/cjcchannel/
On devices with built-in cold-junction compensation (CJC) channels, the CJC channel is read once per sample clock edge.

Deployment - NI-DAQmx 18.6 Manual www.ni.com/documentation/en/ni-daqmx/18.6/mxcncpts/deployment/
Deployment refers to developing an application so that it can be distributed, or deployed, on a different computer than the one on which the application was developed. To deploy an application, you need ...

Handshake Trigger - NI-DAQmx 18.6 Manual www.ni.com/documentation/en/ni-daqmx/18.6/mxcncpts/handtrig/
A Handshake Trigger is a control signal from a peripheral device. The peripheral device asserts the Handshake Trigger to indicate to the DAQ device that it has acquired a sample (for output tasks) or generated ...

Topology - NI-DAQmx 18.6 Manual www.ni.com/documentation/en/ni-daqmx/18.6/mxcncpts/topology/
A switch topology is an abstract representation of the channels and relays in a switch module. The topology establishes the default states for all relays on a module. It also defines the channel names. ...

Connecting Analog Output Signals - NI-DAQmx 18.6 Manual www.ni.com/documentation/en/ni-daqmx/18.6/measfunds/connectaosigs/
Signal connections vary depending on your device, connector block, and signal conditioning module. The following figure shows how to make analog output connections for a typical NI device. For terminals ...

Selecting Read and Write Data Format and Organization - NI-DAQmx 18.6 Manual www.ni.com/documentation/en/ni-daqmx/18.6/mxcncpts/dataformatorganization/
NI-DAQmx provides multiple VIs and functions for reading and writing data. In many cases, you can use multiple options. This section outlines the options and provides some guidelines to follow to select ...

Reference Trigger - NI-DAQmx 18.6 Manual www.ni.com/documentation/en/ni-daqmx/18.6/mxcncpts/referencetrigger/
A Reference Trigger establishes the reference point in a set of input samples. You can configure this trigger to occur on a digital edge, a digital pattern, an analog edge, or when an analog signal enters ...
