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.
Large Infrastructure - 2 Source
Small Infrastructure - 2 Source
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.
RI8546B Device Power Module (DP,VM,DB,VI,VCC)
RI8521B Time Domain Measurement (Waveform)
RI8547A Testset - 2 ports, 6 GHz Test Head
RI8555A Source - 20 GHz Source with Amp Attenuator
RI8553A Measure - 20 GHz Receiver
RI8557A Infrastructure - Large Cassini
