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.

Combiners Icon

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.
