Resource Modulation (Custom OFDM)

Default: See Preset to Standard

The Resource Modulation parameter contains an array of values that specify the modulation type for each "resource" (for every "used" subcarrier and symbol time) in the measurement. Every value in the Resource Modulation array is an index into the QAM Identifier array that is an index into the QAM Levels array that specifies the subcarrier modulation format, see the "Making a Custom OFDM Measurement" tutorial for more information.

You can use the "Load Resource Modulation..." command button to load a text file containing the Resource Modulation type values, see Load Resource Modulation....

Resource Modulating File

The Resource Modulation file The Resource Modulation file specifies the modulation format expected for each subcarrier defined in the Resource Map. contains one Resource Modulation value for every subcarrier defined in the Resource Map file The Resource Map file defines the function of each subcarrier in each symbol, describing whether it is a preamble, pilot, data or null subcarrier.. The Resource Modulation value does not directly specify the modulation format. The Resource Modulation is an index that references a QAM Quadrature Amplitude Modulation Identifier value that is also in index that references a QAM Level value that specifies the subcarrier QAM Level (for example 4QAM, 8QAM, 16QAM... etc.).
