Passive Components
The Passive Components are used to help user during the calibration (Source Power Offset) and the measurement de-embedding step (Input & Output Fixtures).
- Raw Power Offset
Filling up Driver Amplifier hardware, IQSTAR will apply an offset value on each raw (source) power level defined during the calibration and measurement steps. Driver Amplifier information provides a fast method of compensating port power for added attenuation or amplification in the source path. It's an alternative of the Raw Power Calibration:
- For amplification, use positive offset
- For attenuation, use negative offset
- Input & Output Fixtures
The fixtures files can be used when the reference plane of the calibration and the one for the desired data is not the same. In this case, the fixtures can be used to directly de-embed the power waves during the measurements by using the corresponding S2P block files filled in Input & Output Fixtures.
