Notes/Equations

1. The CM_VSA_E444xA_Source model downloads data from any E444xA VSA series instrument when used in vector signal analyzer mode. It outputs different amounts and types of data depending on which measurement you are performing. This model uses the connection manager architecture to communicate with the instrument. See Client-Server Architecture in the Connection Manager documentation for more information.
2. Prerequisites for using CM_VSA_E444xA_Source are:
   • E444x6A Performance Spectrum Analyzer; for information, visit the website http://www.agilent.com/find/psa.
   • Supported method of connecting the instrument to your computer through the Connection Manager architecture. For detailed setup information, refer to Configuring the Server IO on the PC in the Connection Manager documentation.
3. The Instrument parameter specifies a triplet that identifies the specific instrument to be used in the simulation, along with the Connection Manager server information to be used to connect to the instrument.
   To interactively select an instrument, refer to Instrument Selection.
   For more information regarding instrument selection, see Discovering Connected Hardware in the Connection Manager documentation.
4. The Measurement parameter controls what data this model downloads. This model configures its output port based on data.
   Measured time (timed) - IQ measured time data is downloaded and output as timed baseband data in volts.
   Measured spectrum (freq complex) - IQ measured spectrum data is downloaded and output as pairs of complex numbers. The first number is the real frequency (the complex part is zero), and the second number is the complex voltage at that frequency. To separate the signal, place a Distributor2 component at the VSA E444xA output.
5. The ControlSimulation parameter determines how this model acts inside the simulation. When ControlSimulation = YES, this 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 this model. When ControlSimulation = NO, this model produces data ad infinitum, and you must set your sink to control the simulation, then set the Start and Stop parameters to appropriate values.
6. When RepeatData = Repeat, this model downloads data from the instrument once and repeats it; when RepeatData = Resample, this model continues to download data from the instrument. Note that resampled time-based data is not continuous.
