By default, the data from the Analyzer is transmitted in text form. The VISA library has built-in facilities for receiving an array of data from the Analyzer. The example assumes that the size of the array is sufficient to receive a number of elements equal to twice the number of points.
Example of receiving a data array in text format:
double data[NOP * 2]; ViUInt32 retCount; ... retCount = sizeof(data) / sizeof(double); viQueryf(instr, "CALC:DATA:SDAT?\n", "%,#lf", &retCount, data); // retCount now contains the actual number of elements |
