AnalogInputType setting of a SMAI block is set to Current , the
Even if the
MinValFreqMeas setting is still visible. This means that the minimum level for
current amplitude is based on
PP is 20000, the minimum amplitude for current is 20000 * 10% = 2000. This has
practical affect only if the current measuring SMAI would be used as frequency
reference for adaptive DFT which is not recommended, see Setting guidelines.

Note that input and output signals on SMAI_20_2 to SMAI_20_12 are the same
except for input signals GRPx_A to GRPx_N where x is equal to instance number (2
