The Audio Precision GAT-1 is a GPIB/APIB interface translator that enables communication between GPIB-controlled systems and Audio Precision APIB-equipped instruments. It bridges legacy APIB hardware—including System One instruments, switchers, and modules like the DCX 127—into modern automated test setups that rely on GPIB control. The GAT-1 accepts commands from a GPIB controller (typically a computer) and translates them to the Audio Precision proprietary interface bus, allowing unified control of mixed-protocol instrument configurations.
## Technical Specifications
• **Primary Interface:** GPIB (General Purpose Interface Bus, IEEE 488.1)
• **Secondary Interface:** APIB (Audio Precision Interface Bus) — proprietary protocol
## Key Features
• Translates between GPIB and APIB protocols in real time
• Supports Audio Precision System One instruments with GPIB interfaces
• Compatible with APIB-equipped accessories and modules (e.g., DCX 127)
• Maintains legacy instrument functionality within modern test architectures
## Typical Applications
• Integration of older APIB instruments into GPIB-based automated test systems
• Expansion of established Audio Precision configurations without hardware replacement
• Mixed-protocol laboratory setups combining GPIB controllers with APIB peripherals
