The unit called Concat concatenates (appends) all the input data
sets at the various input nodes into a single output set. The first input
is the first set, the second input is next, and so on. The user may use
any number of input nodes.
The input data may be SampleSet, ComplexSampleSet, or other VectorType. The output type is the same as the input. The types of all input sets must be the same. If they are SampleSets or ComplexSampleSets, they must all have the same sampling rate. If any of these conditions is not satisfied, the unit fails. The output for SampleSet or ComplexSampleSet contains the sampling rate and data acquisition time taken from the first input data set. Although the method works for any VectorTypes, it does not make sense for Spectrum, ComplexSpectrum, and Histogram types. The output for VectorType inputs other than SampleSets or ComplexSampleSets is a plain VectorType with no parameters.
