Scalar measurements are measurements on waveforms that produce a single value result. For example, you could use a scalar measurement to find the voltage amplitude or the median voltage of an acquisition.

The following is a categorized list of NI-SCOPE Scalar Measurements. The LabVIEW name is shown first, followed by the equivalent C/C++ name.
