Generate the Voltage or Current You Need

With wide current and voltage ranges, plus 10 mA and 10 mV resolution, the PWS2000 Power Supply Series satisfies a wide variety of applications. Low-noise linear regulation and 0.05% voltage accuracy provide the clean, accurate power you need at a price you can afford.

Prevent Damaged Circuits and Lost Test Time

The numeric keypad makes it easy to specify a precise current limit before you start your test. You can also specify a maximum output voltage, which will prevent accidental voltage settings above the specified maximum. 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 PWS2000 Power Supply Series is designed with the ease-of-use and familiar operation you expect from Tektronix.

Intuitive Operation

The direct-entry numeric keypad makes it easy to enter precise voltage and current values. Up/Down controls, with variable step-size, allow you vary output parameters in an increment size you choose.

Bright Display

A bright vacuum fluorescent display with large digits provides excellent readability at a distance, at an angle, or under dim lighting conditions.

Setup Memories

You can save your instrument settings in one of the 20 internal memory locationss by simply pressing the Save button. Each time you want to recall that setting, just push the Recall button and choose the desired preset.

Performance You Can Count On

In addition to industry-leading service and support, the PWS2000 Power Supply Series comes backed with a three-year standard warranty.
