This chapter describes the model source instruments. This are components which generate a "behavior model" for a specific real-world component.
This behavior model can be a S parameter file with sweeped frequency and - if decided - also sweep power.

|
The component will control a Vector Network Analyzer and create a S parameter file for a 1-Port / 2-Port / 3-Port / 4-Port DUT.

The
sweep direction is taken from LevelStart and LevelStop,
the sign of LevelStep is ignored and will be assigned to match the sweep
direction derived from LevelStart and LevelStop. |
1) |
RunPreSim and RunPostSim determine if the communication with the instrument
shall be done before and/or after the simulation of the circuit. |
2) |
If RunPreset
is selected, the instrument will be reseted and all channel assignments, …
will be executed before other settings are performed on the instrument. |
3) |
If RunRFSetup or RunPreset is selected, the settings for FreqStart, FreqStop, and FreqStep will be executed. |
4) |
The data from the instrument are always stored as S1P / S2P / S3P / S4P files with the name "RS_SxP.sxp" (x=1..4) in the "\data" directory of the current project. |
The component will control a Vector Network Analyzer and create a S parameter file for a 2-Port DUT. Additionally, the power at the ports will be sweeped according to the settings.
