3706A-SNFP

Modular switching and data acquisition system, 6-slot mainframe, up to 576 multiplexer channels, without display and keypad

The Model 3706A system switch with high-performance DMM contains six slots for plug-in cards in a compact 2U high enclosure that 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 result is a tightly integrated switch and measurement solution that’s equally at home on the bench or in the rack. 

The 3700A series comprises four variants of the data logger mainframe 3706A, whereby two basic devices are equipped with an integrated 7½-digit high-performance digital multimeter (DMM). All basic units 3706A each contain six slots for plug-in modules in a compact housing that is only 2 U high.

When fully populated, a mainframe 3706A-SNFP can support up to 576 multiplexer channels with two lines, offering unprecedented channel density and cost savings per channel. The result is a fully integrated switching and measurement solution that is equally suitable for use in the laboratory or in a rack.

Maximises System Control and Flexibility

To provide users with greater versatility when designing test systems, the Series 3700A mainframes are equipped with many standard features. For example, easy connectivity is supported with three remote interfaces: LXI/Ethernet, General Purpose Interface Bus (GPIB), and Universal Serial Bus (USB). Fourteen digital I/O lines are also included, which are programmable and can be used to control external devices such as component handlers or other instruments. Additionally, system control can be greatly enhanced by using our Test Script Processor (TSP) technology. This technology provides “smart” instruments with the ability to perform distributed processing and control at the instrument level versus a central PC.

High-Quality Switching at a Value Price

The Series 3700A builds upon Keithley’s tradition of producing innovative, high-quality, precise signal switching. This series offers a growing family of high-density and general-purpose plug-in cards that accommodates a broad range of signals at very competitive pricing. The Series 3700A supports applications as diverse as design validation, accelerated stress testing, data acquisition, and functional testing.

High Performance, 7½-digit Multimeter (DMM)

The high-performance multimeter option provides up to 7½-digit measurements, offering 26-bit resolution to support your ever-increasing test accuracy requirements. This flexible resolution supplies a DC reading rate from >14,000 readings/second at 3½ digits to 60 readings/ second at 7½ digits to accommodate a greater span of applications. The multimeter does not use a card slot, so you maintain all six slots in your mainframe. In addition, the multimeter is wired to the mainframe’s analogue backplane, ensuring a high-quality signal path from each card channel to the multimeter.
