9SOLUTIONS FOR SCIENTIFIC AND ENGINEERING RESEARCH
Highest Performance 
Parameter Analyzer
Keithley's 4200A-SCS is a modular, 
customizable, and fully-integrated 
parameter analyzer that provides 
synchronized insight into current-
voltage (I-V), capacitance-voltage 
(C-V), and ultra-fast pulsed I-V 
electrical characterization. Its optional 
4200A-CVIV Multi-switch module 
enables effortless switching between 
I-V and C-V measurements without 
re-cabling or lifting prober needles. 
Offering up to 2X faster characterization 
insight, the 4200A-SCS accelerates 
testing of complex devices for materials 
research, semiconductor device design, 
process development or production.
Keithley also offers the industry's 
most complete line of picoammeters, 
electrometers and nanovoltmeters 
for highly sensitive voltage, current 
and resistance measurements for 
nanoscience applications.

Source-Measure Units- 
(SMU) Instruments
Source-measure units or SMUs 
are ideal instruments for making 
nanoscopic material and device 
measurements. They are a smart 
alternative to separate power 
supplies and digital multimeters 
(DMMs). Keithley SourceMeter®SMU 
instruments combine a power supply, 
true current source, 6.5-digit DMM, 
arbitrary waveform generator, V or I 
pulse generator with measurement, 
electronic load and trigger controller 
in one instrument with a convenient 
DMM-like user interface.
A source and measure unit can rapidly 
switch from outputting a specified 
voltage and accurately measuring 
the resulting current, to the other 
way around. When materials such as 
carbon nanotubes (CNTs) or graphene 
are in a high impedance state, the 
SMU can source voltage and measure 
current quickly and accurately. When 
the material is in a low impedance 
state, the SMU can quickly reconfigure 
to source current and measure 
voltage. Furthermore, the SMU has a 
current compliance function that can 
automatically limit the DC current level 
to prevent damage to the material or 
device under test (DUT).
From 3000V to 10nV and 50A pulse to 
1fA, Keithley's family of SourceMeter 
SMU instruments offers the broadest 
measurement range available. Each is 
fully programmable and provides higher 
precision, resolution and flexibility for 
materials research, semiconductor 
devices (transistor, BJT, diode, power 
MOSFET, power semi, LED), electronic 
circuits, and more.
