Audio Precision PSIA-2722 Serial Interface Adapter
The Audio Precision PSIA-2722 Serial Interface Adapter is meticulously engineered to bridge the gap between chip-level devices and the advanced Audio Precision 2700 Series and System Two Cascade Plus audio analyzers. This versatile device enables seamless integration with a variety of components, including analog-to-digital converters, digital-to-analog converters, and sample rate converters, accommodating multiple interface protocols, logic families, and voltage levels.
Versatile Connectivity
Designed for optimal flexibility, the PSIA-2722 supports a wide array of parameters, ensuring compatibility with nearly any device under test. Configuring these parameters is straightforward, thanks to intuitive soft Transmitter and Receiver panels available within the analyzer control software. Test setups are easily saved as part of the analyzer’s test file, allowing for repeatable and consistent performance during measurements.
Enhanced Debugging Features
With an integrated Loop-Back mode, the PSIA-2722 simplifies debugging procedures. Users can easily copy transmitter settings to the receiver with a single click, which streamlines the setup process. The entire configuration can be saved and recalled alongside your test files, ensuring efficient testing workflows.
Compact and Convenient Design
Housed in a slim rack-width package, the PSIA-2722 is designed for convenient placement on top of the host analyzer system. The front-panel BNC connectors facilitate reliable data integrity, while dedicated oscilloscope probe jacks for each BNC signal enhance testing capabilities. Additionally, LEDs above each BNC connector visually indicate data direction, providing quick status updates during operation.
Advanced Parameter Control
All device parameters are easily adjustable using soft panels, allowing users to configure clock rates, word width, formats, and data channels with ease. Each panel is designed for both transmit and receive functions, with a convenient copy settings feature for quick setup adjustments.
