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 mV_p-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.

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.

The PWS4000 Power Supply Series is designed with the ease-of-use and familiar operation you expect from Tektronix.

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.

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.

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.

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.

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, 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.
