Improve Resistance Measurements with 6-Wire Technique
The concept of a basic resistance measurement is to either source a known current across a resistor and measure the voltage drop or vice versa. Testing methods become difficult when the resistor under test (RUT) is in a network, in which case, some method of guarding the RUT is required. This method is known as a 6-wire measurement.

Tutorial: Octave Analysis in the LabVIEW Sound and Vibration Toolkit
Learn about octave analysis functions in the LabVIEW Sound and Vibration Toolkit. This technique, a method of spectral analysis for examining sound and acoustics, slices the spectrum into a set of bands and depicts the energy on a log scale. Doing so facilitates the comparison of spectra and produces results that relate to the response of the human ear.
