Cassini isn’t just modular instruments, it’s a modular architecture and there’s a difference. Test Instrument Modules (TIMs) provide the building blocks for a configurable microwave system with resource ports designed to integrate seamlessly, creating a flexible instrument architecture. This gives Cassini drop in measurement capability and frequency extension as well as instant multi-site expansion with all the DC, mixed signal, and communication pins that an IC might need.

Signal Combination
These instruments extend the capability of microwave sources by providing signal routing and signal conditioning features. Two input sources can be routed out of 4 different outputs for increased port efficiency. Built-in step attenuators and amplifications extends the dynamic range of traditional sources providing 150dB of adjustable dynamic range. Precision microwave combiners enable two-tone signal delivery for high performance intermodulation and linearity test setups.

Receiver
The hub for all measurements on Cassini, the synchrodoyne vector receiver provides direct measure ports for 100 kHz to 25 GHz signals. The local oscillator can be shared with up to three different frequency converting Testsets along with their corresponding downconverted IF signals to provide cross-instrument, phase-coherent measurements.
