Keithley 3706A High Performance Digital Multimeter (DMM) with Six Slots - Keithley 3760, The Keithley 3760 high current multiplexer card has 10 2-pole channels and features 5A contacts. The switching is designed to maintain current paths for signals not connected to the output or, when internal jumpers are removed, to provide high input resistance for making voltage measurements. The 3760 does not connect to the 6 common buses on the 3706A backplane. Daisy chaining cards can be achieved by using an output channel. Typical applications include semiconductor testing, materials research, power supply testing, solar cell measurements,electrochemical applications and IC testing are amongst the capabilities of the 3760 High Current Multiplexer Card.
