Datasheet Series 2280S Precision Measurement, LowNoise, 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 32V at up to 6A the 2280S-60-3 can output up to 60V at up to 3.2A. Both supplies use linear regulation to ensure low output noise and superior load current measurement sensitivity. A high resolution color Thin Film Transistor (TFT) screen displays a wide range of information on measurements. A Tektronix Company 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, Key Features built-in plotting functions allow monitoring trends such as drift. These supplies provide the flexibility required for Monitor load currents from 100nA to 6A with both benchtop and automated test system applications. high accuracy For example, they provide a list mode, triggers, and other Measure voltage and current with 6-digit resolution speed optimization functions to minimize test time in Capture dynamic load currents as short as 140s automated testing applications. Output up to 192W of low noise, linear regulated power DMM-Quality Low Current Programmable rise and fall times eliminate voltage Measurements with High Resolution overshoot and undershoot transients Unlike conventional power supplies, Series 2280S Built-in graphing simplifies analyzing trends or supplies can also make measurements with up to 6 displaying voltage or current waveforms digits of resolution. Voltage output measurements can be High resolution TFT display and soft-key/icon-based resolved down to 100V. These supplies measure load user interface simplify power supply operation currents from 100nA to amps and can resolve down to Programmable output sequences reduce test times 10nA. Four load current measurement ranges (10A, 1A, 100mA, and 10mA) support measuring a devices full Sink up to 0.45A to discharge voltage quickly load current, standby mode current, and small sleep mode Digital I/O for direct communication with other devices currents with DMM-quality accuracy. The high resolution and instruments allows characterizing small changes in load currents with GPIB, USB, and LAN interfaces confidence. It also makes it possible to make a broad Built-in web page simplifies automated control/ range of measurements on a single range with excellent monitoring accuracy across both low and high current values. Automate tests easily with KickStart start-up softwareDatasheet Delay Measure Delay Measure Trigger Trigger Figure 1. Make time-critical measurements on fast-changing or pulse-like loads. An external trigger initiates the acquisition. Programmable delay and measure times enable measurements at a specific time on the load current pulse. In addition to the digital trigger, a level threshold setting can be used to store up to 2500 measurements at a programmed reading rate. Measure Rapidly Changing Loads View and Control Every Parameter of the Supply for Maximum To monitor fast-changing and pulse-like load currents properly, Series 2280S supplies offer the speed necessary Performance to capture load changes that occur at intervals as short as The bright, 4.3-inch TFT display shows voltage and 140s. This capability allows designers and manufacturers current readings, the source settings and many additional of portable, battery-operated devices to monitor load settings in large, easy-to-read characters. The icon- currents easily in all of a devices operating modes so they based main menu provides all the functions users can can determine the devices total power consumption. control and program for fast access to source setup, This high speed measurement capability allows measuring measurement setup, display formats, trigger options, each state of a power-up load sequence and a power- and system settings. Menus are short, and the menu down sequence. Measurements can be made as fast options you need are easy to find and clearly described, as 2500 readings per second, making it possible to so that you can set up test parameters quickly by using characterize and test the current draw at each of the start- the navigation wheel, keypad, or soft-keys. Many set-up up states. parameters, such as for voltage and current settings, can be entered directly from the home screen less complex tests dont even require accessing the main menu to make adjustments. Whether your tests requirements are uncomplicated or complex, the Series 2280S supplies provide a simple way to set up all the required parameters. Figure 2.
