This unit
The Keithley 7059 is a 10-channel low-voltage scanner card engineered for plug-in integration into Keithley Model 705 and Model 706 mainframes. It delivers high-density switching of low-level signals with minimal thermal voltage error, making it ideal for thermocouple and low-level transducer measurements in automated test systems. The card expands channel capacity cost-effectively while maintaining signal integrity through exceptional isolation and low contact potential.
