Choose Your Voltage and Current –
Quickly, Precisely
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.
A wide current and voltage range, and flexible 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 supply’s output value. Remote sense capability to eliminate
the effect of voltage drop in your lead wires and noise of less than 5 mVp-p
further ensures accurate power delivery. List mode and a USB port for
remote programming accelerate complex test development. The PWS4000
Power Supply Series generates the power you need for your application –
quickly and precisely.
Accelerate Complex 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.
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.
Connect Your Bench for Intelligent Debug
You can use your preferred programming environment 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 for basic instrument control, data
logging, and analysis. The optional Professional Edition offers over 200
built-in functions that provide additional signal processing, advanced
analysis, sweeping, limit testing, and user-defined step capabilities.
Setting an appropriate current limit can be critical for preventing damage to
your device under test. With the PWS4000 numeric keypad, you can quickly
and precisely specify a current limit before you start your test. The current
limit is always visible on the display to keep you aware of this important
setting. A user-definable password allows you to lock the front panel to
prevent unwanted adjustments during critical tests.
Designed to Make Your Work Easier
SignalExpress supports the range of Tektronix bench instruments*1,
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 requiring
multiple instruments, and easily capture and analyze your results, all
from your PC. Only Tektronix offers a connected test bench of intelligent
instruments to simplify and speed debug of your complex design.
The PWS4000 Power Supply Series is designed with the ease-of-use and
familiar operation you expect from Tektronix.
Intuitive Operation
A rotary knob, with user-selectable step size, makes it easy to check circuit
response to changing voltage or current. The direct-entry numeric keypad
simplifies setting precise voltage and current values.
Bright Display
Performance You Can Count On
In addition to industry-leading service and support, the PWS4000 Power
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.
Supply Series comes backed with a three-year standard warranty.
