Series 2280S Precision Measurement,
Low Noise, Programmable DC Power Supplies
The Series 2280S Precision Measurement, Low Noise,
Programmable DC Power Supplies are much more than
just sources of clean power; they are also precision
measurement instruments. They can source stable, low
noise voltages as well as monitor load currents over
a wide dynamic range from amps to nanoamps. The
2280S-32-6 can output up to 32 V at up to 6 A; the
2280S-60-3 can output up to 60 V at up to 3.2 A.
Both supplies use linear regulation to ensure low output
noise and superior load current measurement sensitivity.

Soft-key buttons and a navigation wheel combine with the
TFT display to provide an easy-to-navigate user interface
that speeds instrument setup and operation. In addition,
built-in plotting functions allow monitoring trends such
Key Features
as drift. These supplies provide the flexibility required for
both benchtop and automated test system applications.
For example, they provide a list mode, triggers, and other
speed optimization functions to minimize test time in
automated testing applications.
• Monitor load currents from 100 nA to 6 A with
high accuracy
• Measure voltage and current with 6½-digit resolution
• Capture dynamic load currents as short as 140 µs
• Output up to 192 W of low noise, linear
regulated power
DMM-Quality Low Current
Measurements with High Resolution
• Programmable rise and fall times eliminate voltage
overshoot and undershoot transients
Unlike conventional power supplies, Series 2280S
• Built-in graphing simplifies analyzing trends or
displaying voltage or current waveforms
supplies can also make measurements with up to 6½
digits of resolution. Voltage output measurements can be
resolved down to 100 µV. These supplies measure load
currents from 100 nA to amps and can resolve down to
10 nA. Four load current measurement ranges (10 A, 1 A,
100 mA, and 10 mA) support measuring a device’s full
load current, standby mode current, and small sleep mode
currents with DMM-quality accuracy. The high resolution
allows characterizing small changes in load currents with
confidence. It also makes it possible to make a broad
range of measurements on a single range with excellent
accuracy across both low and high current values.
• High resolution TFT display and soft-key/icon-based
user interface simplify power supply operation
• Programmable output sequences reduce test times
• Sink up to 0.45 A to discharge voltage quickly
• Digital I/O for direct communication with other devices
and instruments
• GPIB, USB, and LAN interfaces
• Built-in web page simplifies automated control/
monitoring
• Automate tests easily with KickStart start-up software
