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.
