The system block diagrams are helpful for creating test plans and understanding how the RI Test system performs the actual measurements. The RF path block diagrams include individual diagrams for the TIMs, Infrastructure, and Test Head.



Your Cassini's configuration may vary depending on the TIMs included and the Fixture configuration.

Test Instrument Modules (TIM)
Cassini's TIMs and Testhead diagrams are included below. The model number may be different depending on the capabilities of a TIM, but the functional block diagram should be identical.
