Notes/Equations

1. The SDFRead model reads an SDF file and outputs the contents as timed data. The carrier frequency and timestep are set from the file.
2. The ControlSimulation parameter determines how the model acts inside the simulation. When ControlSimulation = YES, the model keeps the simulation running during the first pass through the data. If your sinks are set to not control the simulation, these automatically collect all data from the model. When ControlSimulation = NO, the model produces data ad infinitum, and you must set your sinks to control the simulation, then set the Start and Stop parameters to appropriate values.
3. By default, the model repeats data from the file. If Periodic = NO, the model outputs 0 until the end of the simulation.
4. The AllPoints parameter is only relevant if the SDF file contained frequency data. Setting this parameter to YES causes data in the unaliased region to be output as well.
5. The DataRecord parameter controls which data record inside the SDF file to output. Most SDF files only contain one data record, so you can usually leave this parameter set to its default of 1.
