New Keithley System
Switch Platform Offers High Throughput Signal Switching, LXI Class B, and Optional High-Performance
Cleveland, Ohio – September 13, 2007 -
Keithley Instruments, Inc. (NYSE:KEI), a leader in solutions for emerging measurement needs,
announces the release of the Series 3700 System Switch/Multimeter and Plug-in Card Family,
Keithley's next-generation platform of switching and integrated digital multimeter (DMM) test
solutions. It offers high quality, instrument grade switching for a wide variety of applications,
including the performance demands of high channel count applications, with its ability to control up
to 576 multiplexer channels in an industry-leading six-slot, 2U form factor. A high-performance
integrated DMM option provides fast, low-noise measurements with resolutions up to 7½-digits at a
price lower than typical 6½-digit DMMs. To learn more about the Series 3700 and to view a short
product demo, visit www.keithley.com/pr/076.
The Series 3700 System Switch/Multimeter solutions offer scalable, high-performance switching and
multi-channel measurements that are optimized for automated testing of electronic products and
components. Together with a growing family of plug-in switch and control cards, the Series 3700 is
ideal for either a functional test system or in stand-alone data acquisition and measurement
applications for production and functional testing of electronic products and devices, especially
multi-channel I-V testing and accelerated stress tests.
The Series 3700 is available with four different mainframe options for added flexibility. For
instance, users can choose a mainframe without the integrated DMM as well as one without a
front-panel display and keypad. The optional integrated DMM eliminates the need to manually
coordinate an external DMM with a switch topology, freeing up valuable development time. Also, a USB
2.0 port on the front panel provides "transportable memory" that allows users to save measurements
to non-volatile memory.
The base Model 3706 features an integrated 7½-digit, high-performance DMM. In addition to
supporting 13 built-in measurement functions, measurement ranges are expanded to include a 1-Ohm
low-resistance range and a 10-μAmp low-current range. The Model 3706 mainframe contains a
multi-processor architecture to maximize measurement speed and system throughput. It features a
single-channel reading rate that ranges from greater than 10,000 DCV/two-wire Ohms readings per
second at 3½-digit resolution to 60 readings per second at 7½-digit, 26-bit resolution if needed.
The Series 3700 also incorporates Keithley's Test Script Processor (TSP™) technology.
TSP redefines the traditional boundaries of test instrumentation by bringing PC-like
functionality into the instrument. For example, users can create test scripts that are embedded in
and executed within the instrument. These test scripts can contain complete test routines, including
complex decision making and instrument control, enabling the instrument to perform autonomously. In
addition, Keithley provides a free software tool, Test Script Builder, for conveniently writing,
managing, and debugging test scripts. This distributed processing technology reduces PC
intervention, eliminating bus latency issues and improving test throughput and flexibility. For
applications where throughput and timing synchronization is not required, TSP also gives users added
flexibility by executing single line commands just like traditional instruments.
One important supporting technology for TSP is TSP-Link™, a communication bus that allows
multiple TSP instruments to be configured in a master/slave network. TSP-Link offers the capability
to expand a test system, allowing TSP-enabled instruments such as the Series 3700 and Series 2600
SourceMeter® Instruments to be scaled according to present or future testing needs. Such TSP-enabled
instruments give test engineers the fundamental building blocks for designing tightly integrated,
high throughput ATE systems.
The Series 3700 System Switch/Multimeter is the first LXI Class B compliant system switch on the
market. It includes a 10/100M Base-T Ethernet connection, LAN-based instrument triggering, and
precision time protocol (PTP) synchronization. PTP synchronization, a unique feature not available
on LXI Class C compliant instruments, allows multiple Class B-enabled instruments to be time
synchronized for consistent time stamping and event coordination. An interactive graphical Web
server gives users a quick and easy method to operate, troubleshoot, and learn how to use the
instrument. The Series 3700 also offers additional programming interfaces, including USB and GPIB
The Series 3700 also includes six new optional high-density and general-purpose plug-in cards
that accommodate a broad range of signals and topologies including multiplexer, matrix, and isolated
switch functions. The Model 3720 and Model 3721 are dual 1X30 and dual 1X20 multiplexer cards
respectively for general purpose switching. The Model 3722 is a dual 1X48 high density multiplexer
card ideal for general purpose switching applications that require a high channel count. The Model
3723 is a dual 1X30 high speed multiplexer card using high-speed, long-life reed relays with
actuation times of less than 0.5msec. Keithley's Model 3730 6X16 high density matrix card provides
96 two-pole cross points. Lastly, the Model 3740 is a 32 channel isolated switch card ideal for
routing power signals or other high current signals. When fully loaded, the Series 3700 mainframe
supports up to 576 two-wire multiplexer channels for industry-leading channel density, which saves
precious rack space and lowers cost of test. Keithley will be adding more plug-in cards to the
Series 3700 Family in 2008.
Price and Availability. Keithley's Series 3700 System Switch mainframe starts at $1,790 USD.
Plug-in cards start at $925 USD. Availability is about six weeks ARO, effective immediately.
