Roos Instruments, Inc.

Cassini is a modular automated test equipment (ATE) platform that was introduced by Roos Instruments in 2005. It offers a wide range of capabilities, including DC and high-speed digital measurements, RF measurements up to 110 GHz, and mixed-signal measurements. Cassini is also highly configurable, allowing users to tailor it to their specific test needs.

One of the key features of Cassini is its graphical programming environment. This environment makes it easy to create complex test plans without having to learn a complex programming language. Cassini also includes a number of features that help to improve test efficiency, such as testplan optimization and adaptive limits.

Cassini is used by a wide range of industries, including telecommunications, aerospace, and defense. It is a proven platform that can be used to test a wide variety of electronic devices.

Here are some of the key benefits of using Cassini ATE:

• Wide range of capabilities: Cassini can be used to test a wide variety of electronic devices, from DC and high-speed digital devices to RF and mixed-signal devices.
• High configurability: Cassini is highly configurable, allowing users to tailor it to their specific test needs.
• Graphical programming environment: Cassini's graphical programming environment makes it easy to create complex test plans without having to learn a complex programming language.

If you are looking for a powerful and flexible ATE platform, Cassini is a great option. It offers a wide range of capabilities, high configurability, and a graphical programming environment that makes it easy to create complex test plans.

Accuracy at the Device

Cassini’s software manages the calibration layers automatically. As fixtures and device interface boards are interchanged with the test system, each calibration layer is cascaded to extend the calibrated measurement plane for port match and signal loss correction. This guarantees an accurate and repeatable test setup on the production floor for any device application.

Configurable Resource Mapping

With the ability to configure and reconfigure the device interface, Cassini’s software helps manage all of complexity. You define serialized signal paths, resource switch controls, and additional measurement resources and the system automatically links calibrated paths together.

Taking Modular to a Whole New Level

A modular test system is only as modular as it's least configurable component. All of the functionality and capability of traditional load boards have been re-engineered to take advantage of the configurable instrument framework of Cassini. The discrete layers enable maximum design flexibility for high performance RF devices that can adapt to changing application needs.

Multi‑Instrument Test Done Right

A truly unique aspect of Cassini ATE is the RF system integration layer in the device interface. The 16 universal instruments slots accommodate interchangeable interface blocks and interconnect, allowing the test system’s architecture to be dynamically configured for each device application.

Production Test Bench

Fixtures enable easy access to microwave components while protecting them in a ruggedized, RF-shielded enclosure during production. It also supports expandable instrument capability with fixture module cards such as driver control for electromechanical relays and microwave switches as well as signal attenuation, amplification, and additional parametric measure resources.

Launch Precision Measurement

Interchangeable DC, high-speed digital, and microwave inserts provide precise contact signal launches onto the device interface board.The inserts support a flexible signal topology for customizing to applications and creating symmetric multi-site layouts.

High Frequency Performance

The two-layer PCB and aluminum reinforcement combine high frequency performance and production durability. The design simplifies board layout, reduces the cost of high wear components, and enables quick changeout in production.
