MAKE MULTIPLE MEASUREMENTS ACCURATELY
USING A SINGLE INSTRUMENT
A source measure unit (SMU) instrument is a
ve-in-one tool. It combines the useful features of
a digital multimeter (DMM), power supply,
current source, electronic load and pulse generator,
all in a compact form factor. This empowers you to:
• Precisely source and measure voltage
and/or current at the same time
• Measure resistance vs. current/voltage directly or indirectly
• Source and measure across a very broad range of current
(100aA to 50A) and voltage (100nV to 3 kV) with 6½ digits of measurement resolution
• Run production tests 60% faster and gain up to 10X more throughput
• Save time, maximize speed and get jobs done quickly.
WHY A KEITHLEY SOURCE MEASURE UNIT?
For more than 70 years, Tektronix — the manufacturer of Keithley SMUs — has been
designing, manufacturing and marketing advanced electrical test instruments and systems for
the specialized needs of electronics manufacturers in high performance production testing,
process monitoring, product development and research.

Save Time, Maximize Speed, and Get Jobs Done Quickly
SMU models that use familiar graphical interfaces, like icon-based menu structures, are easier to use for all
experience levels. You’ll make measurements faster by reducing the learning curve and conguration steps,
enabling you to learn faster, work smarter, and invent easier.

MORE USEFUL THAN THE COMBINATION
OF INDIVIDUAL INSTRUMENTS
SMU VS. POWER SUPPLIES
• SMUs can automatically sweep voltage or
current to and from negative and positive
outputs when the source crosses zero.
• During these operations, there is no
need to change test leads.
• Output of a SMU can settle to within
0.01% of the specied accuracy in
as little as 50 ms.
• SMU has higher precision and wider
operating ranges.
• SMU is a more exible option
VS.
SMU VS. THE DMM
AND POWER SUPPLY COMBO
• SMU tightly integrates the source and measure
capability into one instrument, eliminating the
need for a separate DMM
and power supply.
• Improves test times, simplies overall test
system design and increases usability
• SMUs can outperform the DMM and Power
Supply Combo on current vs. voltage (IV)
measurements for a variety
of applications.
