The Keithley 7999-6 is a GPIB-controlled RF relay unit engineered for signal routing and switching in automated test systems. It delivers flexible matrix configurations—either 4×4 or 6×6 input/output—within a single compact assembly, enabling two independent switch matrices in one unit. Control is available via GPIB remote interface or direct front panel switches, with LED indicators monitoring power status, GPIB errors, and relay contact positions. The blocking matrix configuration supports high-density rack integration for complex RF test applications.
## Technical Specifications
• **Matrix Configurations:** 4-input/4-output or 6-input/6-output switching matrices
• **Dual-Matrix Capability:** Accommodates two switch matrices in a single assembly
• **Relay Type:** RF relay switching elements
• **Matrix Type:** Blocking configuration
## Key Features
• GPIB interface for remote automation and system integration
• Front panel switch control for direct local operation
• LED status indicators: power, GPIB error, relay contact positions
• Compact form factor designed for high-density test rack mounting
• Supports independent or cascaded matrix operation
## Typical Applications
• RF signal routing in automated test environments
• Multi-channel RF switching for component and subsystem testing
• High-density test rack configurations requiring compact switching matrices
• Systems requiring both remote and local control of RF signal paths
## Compatibility & Integration
The 7999-6 integrates into Keithley test systems via standard GPIB protocol. Its compact footprint and dual-matrix housing accommodate space-constrained rack configurations while maintaining independent or synchronized operation of switch channels.
