The Keithley 3706A is a High Performance Digital Multimeter (DMM) and contains six slots for plug-in cards in a compact 2U high (89mm) enclosure. The multimeter easily accommodates the needs of medium to high channel count applications. When fully loaded, a mainframe can support up to 576 two-wire multiplexer channels for unrivalled density and economical per channel costs.
The high performance multimeter provides a tightly integrated switch and measurement system that meets the demanding application requirements in a functional test system or provides the flexibility needed in stand-alone data acquisition and measurement applications.
