Important parameters of analog modules
Alongside the type and range of measurement, the precision, resolution and conversion time
are the main points to consider when selecting an analog module. For some applications
such as systems which cover a large area, common mode or channel isolation are also
important. The parameters listed here are examined in more detail in the following pages.
