Measurement data can be either complex values or real values. This depends on the format selected by the user. For example, the data is real in logarithmic magnitude format and complex in polar format.
The measurement data is transferred in a Variant type variable, which represents a Double type array. Two adjacent array cells are used to transfer one complex measurement. To transfer one real measurement, two adjacent array cells are used, but the second cell is always equal to 0. Thus, measurement data array size is a double number of the measurement points.
