Architect the Best Production Test
Fixtures carry the modular architecture of Cassini into the device interface environment. Housed in a rugged aluminum enclosure is a completely configurable test resource environment. It provides a versatile application range from DC to 90GHz and a rapid changeout system in production. Seamless integration with Cassini’s software allow fixtures to extend and enhance the capabilities of test instruments with an integrated calibration layer that guarantees signal accuracy right to the device pin.
Flip the Cost Model
All of the functionality and capability of traditional load boards have been re-engineered to take advantage of the configurable instrument framework of Cassini. Separating the device interface into two layers enables maximum design flexibility for high performance measurements that can adapt to changing application needs cost effectively.
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.
