MinValFreqMeas 5 - 200 % 1 10 Limit for frequency calculation in % of VBase
Even if the AnalogInputType setting of a SMAI block is set to Current,
the MinValFreqMeas setting is still visible. This means that the
minimum level for current amplitude is based on VBase. For example,
if VBase is 20000, the minimum amplitude for current is 20000 * 10%
= 2000. This has practical affect only if the current measuring SMAI is
used as a frequency reference for the adaptive DFT. This is not
recommended, see the Setting guidelines.
