Device calibration consists of verifying the measurement accuracy of a device and adjusting for any measurement error. Verification consists of measuring the performance of the device and comparing these ...

The following figure shows the internal routing for C Series devices used in a cDAQ-9132, 9133, 9134, 9135, 9136, 9137, 9171, 9174, 9178, 9179, 9181, 9184, 9185, 9188, 9188XT, 9189, and 9191 chassis. The ...

When you include channels from multiple C Series modules in a task, NI-DAQmx automatically synchronizes the modules. A task can include channels from multiple C Series modules, given the following conditions: ...

In physical channel names, cDAQ1Mod1 is the default device name for a C Series device plugged into a USB or Standalone CompactDAQ chassis, where cDAQ1 is the default chassis device name, and Mod1 refers ...

C Series devices do not support hardware-timed single-point sample mode or Wait for Next Sample Clock. Analog Input Timing Considerations for C Series Devices You can use multiple analog input devices ...

To determine if a common-mode over-range detection has occurred, use the Common Mode Range Error Channels Exist and Common Mode Range Error Channels properties within the DAQmx Read property node. Common ...

On some devices, you can configure high-speed, high-resolution, or low-noise measurements using the AI.ADCTimingMode attribute/property. The following devices support configurable ADC Timing. FD-11613 ...

This section contains information on counter signal connections and routing diagrams that illustrate the internal counter routing.
