8. Switch Matrix Configurations

Ultra-Low Current/Local Sense Configuration (4200-UL-LS-XX)

The Ultra-Low Current/Local Sense switch configuration is built using the Keithley 7174A Low Current Matrix Card (with the 707B or 708B Switch

Matrix), which is designed for semiconductor research, development, and production applications requiring high quality, high performance switching

of I-V and C-V signals. This configuration provides eight instrument inputs with up to 72 output pins at only 10 fA typical offset current.
