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.
