Product Overview

The 3760 has ten 2-pole channels and features 5 A 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. Semiconductor testing, materials research, power supply testing, solar cell measurements, electrochemical applications and IC testing are among the applications simplified with the 3760 High Current Multiplexer Card.
