3706A Keithley System Switch / Multimeter

The Tektronix / Keithley 3700A Series System Switch/Multimeters offer scalable, instrument grade switching and multi-channel measurement solutions that are optimized for automated testing of electronic products and components. The 3700A Series includes four versions of the Model 3706A system switch mainframe along with a growing family of plug-in switch and control cards. When the Model 3706A mainframe is manufactured with the high performance multimeter, it receives a tightly integrated switch and measurement system that can meet the demanding application requirements in a functional test system or provide the flexibility needed in stand-alone data acquisition and measurement applications.

To provide users with greater versatility when designing test systems, the 3700A Series 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.

The Tektronix / Keithley 3700A Series System Switch/Multimeters build 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. The 3700A Series supports applications as diverse as design validation, accelerated stress testing, data acquisition, and functional testing.

The Tektronix / Keithley 3700A Series System Switch/Multimeters includes the base Model 3706A system switch/multimeter mainframe with three options for added flexibility. This mainframe contains six slots for plug-in cards in a compact 2U high (3.5 inches/89mm) 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 or (2,688) one-pole matrix crosspoints for unrivaled density.

The high performance multimeter option provides up to 7.5-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 3.5 digits to 60 readings/second at 7.5 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 analog backplane, ensuring a high quality signal path from each card channel to the multimeter.

The multimeter supports (13) built-in measurement functions, including: DCV, ACV, DCI, ACI, frequency, period, two-wire ohms, four-wire ohms, three-wire RTD temperature, four-wire RTD temperature, thermocouple temperature, thermistor temperature, and continuity. In addition, the multimeter offers extended low ohms (1W) and low current (10µA) ranges. In-rack calibration is supported, which reduces both maintenance and calibration time.
