Keithley 7077

The Keithley 7077 is an isolated coaxial matrix switch card engineered for integration into Keithley switching systems, specifically the Model 707A mainframe. This 8×12 matrix configuration delivers 96 crosspoints for flexible signal routing in automated test and data acquisition applications. The card’s coaxial design optimizes RF signal transmission while minimizing signal degradation, making it ideal for high-frequency measurement environments.

## Technical Specifications

• **Matrix Configuration:** 8 rows × 12 columns
• **Total Crosspoints:** 96
• **Contact Type:** 2-pole Form A (SPST, normally open)
• **Connector Type:** BNC connectors
• **Signal Optimization:** Coaxial transmission for RF applications

## Key Features

• Isolated coaxial matrix design minimizes crosstalk and signal degradation
• 96 independently addressable crosspoints enable complex signal routing topologies
• BNC connector interface supports standard coaxial cable integration
• Form A contact configuration provides normally-open switching action

## Typical Applications

• RF signal routing and switching in automated test systems
• Multi-channel data acquisition with coaxial signal paths
• High-frequency measurement switching matrices
• Laboratory and production test environments requiring flexible signal distribution

## Compatibility & Integration

The 7077 card is designed for the Keithley Model 707A Switching Matrix mainframe and maintains backward compatibility with the Model 707 mainframe. Integration into either system enables modular expansion of switching capacity within a compact 52 mm × 347 mm × 523 mm (2 in × 13.6 in × 20.6 in) mainframe footprint.
