It accepts an M-ary value that specifies a predefined symbol map with the number of distinct symbol map values to use as symbols. samples per symbol specifies an even, positive number of samples dedicated to each symbol. Multiply this value by the symbol rate to determine the sample rate. The default value is 16. symbol values specifies an array of symbol values with an order that corresponds to the symbol map. The number of QAM states in the array must be 2N, where N is the number of bits per symbol. The length, or magnitude, of the vector for the symbols farthest from the origin must be 1. This VI expects a two-dimensional, square array of integers for the symbol values parameter. 4-QAM expects a 2×2 array (2 rows, 2 columns), 16-QAM expects

The negative number will not be considered as a part of the symbol map. error in (no error) can accept error information wired from previously called VIs. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. code identifies the error or warning code. source describes the origin of the error or warning. QAM system parameters returns parameter values defining the QAM system. Wire this cluster to the corresponding system parameters cluster of the MT Modulate QAM VI or MT Demodulate QAM VI. samples per symbol returns the number of samples per symbol in the modulated output complex waveform. For error-free operation, the samples per symbol should be an even number. symbol map returns an ordered array that maps each symbol value to its desired coordinates in the complex plane. The number of QAM states in the array must be 2N, where N is the number of bits per symbol. The length of the vector for the symbols farthest from the origin must be 1. bits per symbol returns the number of bits represented by each symbol. This value is equal to Log2(M), where M is the order of the modulation (for example, for 16-QAM, M=16). error out passes error or warning information out of a VI to be used by other
