Choose Your Voltage and Current –Quickly, Precisely
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.
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 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
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
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 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.
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.
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.
Performance You Can Count On
In addition to industry-leading
service and support, the PWS4000 Power Supply Series comes backed
with a three-year standard warranty.
