MinValFreqMeas 5 - 200 % 1 10 Limit for frequency calculation in % of
UBase
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 UBase. For
example, if UBase 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.
