Key Features - Tektronix Keithley 2281 Series Reference Manual

Section 1: Introduction

Key features

The 2281S has three basic functions: High-performance power supply, battery test, and battery
simulation.
As a high-performance power supply:

High-current resolution and sensitivity to measure a wide range of load currents

6½-digit measurement resolution to enable a wide range of measurements on a single current range
 Fast current measurements to test or study load current pulses as narrow as 100 μs

Linear mode, low noise output
As a battery test instrument:

Battery capacity test with charging and discharging functions

Battery charge and discharge process and data logging (voltage, current, resistance, and amp-hour
information)

Generate a battery model based on battery test results

Measure open-circuit voltage and resistance
As a battery simulator:

Simulate a real battery based on a battery model

Dynamic and static simulation mode to simulate battery output

Intuitive way to show battery capacity and battery voltage on home screen
Other features:

Color TFT display with icon-based and soft-key user interface

Data logging and analysis with graphical display and statistics for trend analysis

GPIB, USB-TMC, and LAN LXI interfaces for automated test development

Digital I/O for rich trigger functions

Direct parameter entry using the front-panel keypad, soft keys, or the navigation control

Front-panel USB-A connector for flash-drive support

Front and rear inputs with remote sense connections on the rear-panel connector

Overcurrent, overvoltage, and overtemperature protection

Compact, 2U, half rack, stackable form factor fits easily in a test rack
