Keithley 7058
Scanner Card
Description
This Scanner Card is intended for high quality switching of sensitive signal levels for up to 10 channels.
The card is designed to introduce minimal offset current error (under 1pA).
It is engineered to simplify integration into larger test systems for sensitive measurements.
Removable jumpers allow channels to be configured as voltage switches.
Triaxial input connectors provide better shielding and permit direct connection to Keithley electrometers.
