TiePie Handyscope HS5 series, User Manual

Page: 11 / 47

With the accompanying software the Handyscope HS5 can be
used as an oscilloscope, a spectrum analyzer, a true RMS voltmeter
or a transient recorder. All instruments measure by sampling the
input signals, digitizing the values, process them, save them and
display them.
3.1 Sampling
When sampling the input signal, samples are taken at fixed inter-
vals. At these intervals, the size of the input signal is converted to a
number. The accuracy of this number depends on the resolution of
the instrument. The higher the resolution, the smaller the voltage
steps in which the input range of the instrument is divided. The
acquired numbers can be used for various purposes, e.g. to create
a graph.
Figure 3.1: Sampling
The sine wave in figure 3.1 is sampled at the dot positions. By
connecting the adjacent samples, the original signal can be recon-
structed from the samples. You can see the result in figure
3.2 .
