The eBook with 100 pages shows
the basics of electrical measurement technology and the basics of
programming with the LabVIEW graphical programming
language of the company National
Instruments. In the eBook,
the following instruments analog multimeter, digital
multimeter, digital oscilloscope are explained in detail.

It is shown how to measure a DC
voltage or direct current, as well as an AC voltage with an analog and
digital multimeter how to program the different measuring ranges.
How
is a voltage with an A/D-converter digitized. Why do you need fast
A/D-conversions (Nyquist-Shannon law). How to modele an oscilloscope
with a sound card.
A
little math, namely the theory of error-analysis which are explained
here with reference to detailed examples in LabVIEW.

Operating the Oscilloscope is shown based on films
in a virtual
oscilloscope. At the end of eBooks
some important features of LabVIEW are shown using examples (histogram,
save, load, real-time, FFT, etc.). The eBook does not have to explain
the claim LabVIEW, with all its possibilities.
There are already appropriate books on the market. Here we explain the
basics of measurement with LabVIEW.
