Test and Compare Express VIs

Owning Palette: Analysis Express VIs

Use the Test and Compare Express VIs to compare an input signal to user-specified limits.

If a LabVIEW SignalExpress palette is empty or appears to be missing VIs, you are missing components that are not installed by LabVIEW SignalExpress. Reinstall the National Instruments Device Drivers DVD and include NI-DAQmx™ and Modular Instruments support.

The VIs on this palette can return general LabVIEW error codes.

Palette ObjectDescription
Digital CompareCompares a reference and test signal to determine the number of sample errors.
Limit TestTests an input signal or value against user-specified limits and returns information on whether the test passed or failed and, in the case of a failure, where it failed. Limit Test accepts time-domain signals, frequency-domain signals, and scalar values as inputs. You can specify either signals or scalar values for the limits, and you can define the limits or use other signals in the project as the limits.
