Keithley Instruments - Press Release 9-13-2007
New Keithley System Switch Platform Offers High Throughput Signal Switching,
LXI Class B, and Optional High-Performance
Ohio – September 13, 2007 -
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
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.
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 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
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
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.
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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
