Getting started with System Architect
- Perform CW simulation
  How to perform CW simulation. A CW simulation only allows for taking into account the steady-state of the system response. The CW simulation considers that the envelope signal varies slowly over time, with regard to time constants of the system. A CW simulation is much faster than a transient simulation, however it is only possible for CW pulse type excitation, with constant (or slow) amplitude and frequency transition.
- Perform Transient simulation
  How to perform transient simulation. The transient simulation in VISION allows to obtain the time domain response of a non-linear circuit excited by a modulated complex signal.
- Perform Sweep Analysis
- Perfom noise analysis
- Perform statistical analysis
  How to perform statistical analysis. Statistical analysis makes it possible to perform a simulation in which variables or models follow a statistical law.
- Perform model export
  How to perform a model export from System Architect application. The model export make possible to use a model outside from VISION environnment in order to use other kind of analysis tool. The model export is currently interfaced with SystemVue, VSS, Simulink and the Comlib2 module.
- Perform antenna analysis
  - Setup Antenna schematic
    how to perform an antenna-type analysis in VISION? This type of analysis is in fact a mixed electric and electromagnetic type under the assumption of radiation in the far-field. The amplitude and phase control of each patch is possible thanks to the joint use of a particular source block and of the variable block. This allows a precise analysis of the interactions between nonlinear memory blocks located before an antenna and for which the mismatch conditions are taken into account.
  - Antenna simulation results
    how to view the results of an antenna-type analysis in vision. This type of analysis is in fact, a mixed electric/electromagnetic under the assumption of radiation in the far-field. The user is able to consult both the results of the electrical stimulation, such as the incident and reflected powers at each port of the antenna and the radiation pattern of the latter. The proposed graphs take into account the variations established in the VAR block as well as the variations in the azimuth angle (Phi) and elevation (Theta) obtained from the EM simulation files.
- Perform co-simulation with Matlab
  How to perform co-simulation with Matlab. VISION allows to set up co-simulation process using Matlab API block.
- Perform 2-tone simulation
  How to perform 2-tone simulation. 2-tone simulation in VISION allows to obtain time domain response of nonlinear circuit excited by 2-tone complex signal varying in frequency spacing and average power.
- Perform Transient simulation based on IQ measurement
  This manual describes the procedure for using IQ measurements obtained from IQSTAR software to perform transient simulation. The transient simulator in VISION allows for obtaining the time domain response of a non-linear circuit excited by a modulated complex signal which can then be compared to measurement data from IQSTAR.
- Perform Transient simulation using IWF file and IQ probe
  How to perform transient simulation using UWF file generated from topics/waveform_generator.html tool. The transient simulation in VISION allows to obtain the time domain response of a non-linear circuit excited by a modulated complex signal.
- Perform Parameterized SnP Simulation
  How to perform a simulation involve parameterized SnP component in System Architect application. The blocks are used to simulate, interpolate and extrapolate discretized SnP data along one or more control data (i.e. parameters)..
- Perform Tunable Filter Simulation
  How to perform a simulation involve tunable filter in System Architect application. The blocks are used to simulate, interpolate and extrapolate discretized S2P data along one control data in continous mode.
- Perform LoadPull Simulation
  To perform a Load Pull simulation, the "IDEAL TUNER" block(See topics/Ideal_tuner.html#Ideal_tuner) generates a file with a pattern of impedances, which can be added to "ERHO" block at the end of the schematic. The impedance is then swept using the VAR block, which varies the index of the impedance in the file created by the ideal tuner. The load can be defined in either magnitude and phase format or real and imaginary format...
