Keithley 707 Switching Matrix Mainframe

The Keithley 707 Switching Matrix Mainframe is an expandable modular platform engineered for signal routing and switching in automated test, data acquisition, and research environments. This rack-mountable mainframe accepts a range of Keithley Series 700/7000 switch cards, enabling configuration of diverse signal paths across analog, digital, and RF applications. The system supports multiple independent switching matrices or single large-matrix configurations depending on card selection, with matrix sizes ranging from 4×16 through 16×16 and larger via chassis expansion.

Control is provided via GPIB (IEEE-488), with optional Ethernet and serial interfaces available depending on configuration. Signal integrity is maintained across switching configurations; bandwidth, isolation, and insertion loss depend on installed switch cards. Switching speed varies with card type and switching operation complexity.

Power consumption scales with installed cards and operational load.
