Choose Your Voltage and Current –
Quickly, Precisely
A wide current and voltage range, and flex ible features, make the PWS4000
Power Supply Series a versatile addition to your bench. With 0.03% basic
voltage accuracy and 0.05% basic current accuracy, you can be confident
in the power su

further ensures accurate power delivery. List mode and a USB port for
remote programming accelerate complex test develop ment. The PWS4000
Power Supply Series generates the power you need for your application –
quickly and precisely.

Total Control Over Your Output
All models of the PWS4000 Series include an overvoltage protection circuit
that reduces the output voltage if it exceeds a user-specified threshold for
any reason. The PWS4000 Series also allows you to prevent the voltage
from being accidentally adjusted above a limit that you specify.
Setting an appropriate current limit can be critical for preventing da m age to
your device under test. With the PWS4000 numeric keypad, you can quickly

simplifies setting precise voltage and current values.
Bright Display
A bright vacuum fluorescent display provides excellent readability at a
distance, at an angle, or under dim lighting conditions. Meter readings and
limits are always visible. You don’t need to push buttons just to see your
limits.

Setup Memories
To save time when repeating tests, you can save your instrument settings in
one of the 40 internal memory locations by simply pressing the Save button.
Each time you want to recall that setting, just push the Recall button and
choose the desired setup.
Accelerate Comple x Test Development
The built-in List mode allows you to define a custom sequence of voltage
and current steps for your test. You can define up to 7 lists, and each list can
have up to 80 steps. Lists can be configured to step through the sequence
based on external triggers or front-panel button presses. Alternatively, you
can specify a duration for each step and the instrument will automatically
step through the sequence. For even more flexibility, a USB device port on
the back panel makes it easy to connect the power supply to your PC for
remote programming.
Connect Your Bench for Intelligent Debug
You can use your preferred programming enviro nment to control the
PWS4000 using a USBTMC-compliant device port, or you can get quick
results with the special Tektronix Edition of National Instrument’s LabVIEW
SignalExpress™ software. The PWS4000 Power Supply Series includes
the Tektronix Edition of SignalExpress f or basic instrument control, data
logging, and analysis. The opt ional Professional Edition offers over 200
built-in functions that provide additional signal processing, advanced
analysis, sweeping, limit testing, and user-defined step capabilities.
SignalExpress supports the range of Tektronix bench instruments*
enabling you to connect your entire test bench. You can then access the
feature-rich tools packed into each instrument from one intuitive software
interface. This allows you to automate complex measurements re quiring
multiple instruments, and easily capture and analyze your results, all
from your PC. Only Tektronix offers a connected test ben ch of intelligent
instruments to simplify and sp eed debug of your complex design.
