2280S-32-6

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 Model 2280S-32-6 can output up to 32V at up to 6A; the Model 2280S-60-3 can output up to 60V at up to 3.2A. • Measure small load currents with 0.05% accuracy and 10nA resolution • Measure voltage and current with 6½-digit resolution • Capture the peak of a load current burst as short as 140µs using external triggering or capture load current changes using a level threshold, sampling at 2800 readings per second • Output up to 192W of low noise, linear regulated power • Programmable rise and fall times eliminate voltage overshoot and undershoot transients • Built-in graphing simplifies analyzing trends or displaying voltage or current waveforms • High resolution TFT display and soft-key/icon-based user interface simplify power supply operation • Programmable output sequences reduce test times 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. 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 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. DMM-Quality Low Current Measurements with High Resolution Unlike conventional power supplies, Series 2280S supplies can also make measurements with up to 6½ digits of resolution. Voltage output measurements can be resolved down to 100µV. These supplies measure load currents from 100nA to amps and can resolve down to 10nA. Four load current measurement ranges (10A, 1A, 100mA, and 10mA) 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. Measure Rapidly Changing Load Currents Capture measurements with either an external control signal or an analog level threshold crossing Precision measurement, low noise, programmable DC power supplies Precision Measurement, Low Noise, Programmable DC Power Supplies To monitor fast-changing and pulse-like load currents properly, Series 2280S supplies offer the speed necessary to capture load changes that occur at intervals as short as 140µs. This capability allows designers and manufacturers of portable, battery-operated devices to monitor load currents easily in all of a device’s operating modes so they can determine the device’s total power consumption. This high speed measurement capability allows measuring each state of a power-up load sequence and a power-down sequence. Measurements can be made as fast as 2500 readings per second, making it possible to characterize and test the current draw at each of the start-up states. Delay Measure Delay Measure • Sink up to 0.45A to discharge voltage quickly • Digital I/O for direct communication with other devices and instruments • GPIB, USB, and LAN interfaces • Built-in web page allows automated control, monitoring, and data logging • Automate tests easily with KickStart start-up software 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. 1.888.KEITHLEY (U.S. only) www.keithley.com A Greater Measure of Confidence A Tektronix Company DC POWER SUPPLIES Precision measurement, low noise, programmable DC power supplies Series 2280S No da enh w w t a an i t lo c e h gg d in g DC POWER SUPPLIES Precision measurement, low noise, programmable DC power supplies Ordering Information 2280S-32-6 Precision Measurement DC Power Supply, 32V, 6A 2280S-60-3 Precision Measurement DC Power Supply, 60V, 3.2A Accessories Supplied Quick Start Guide KickStart Quick Start Guide User Documentation CD LAN Crossover Cable Power Cord Rear Panel Mating Connector with Cover ACCESSORIES AVAILABLE 2280-TEST-LEAD Power Supply Test Lead Kit, 1000V, 20A Rating 2280-001 Rear Panel Mating Connector and Cover CA-180-3A LAN Crossover Cable USB-B-1 USB Cable Type A to B, 1m (3.3 ft) 2450-TLINK Trigger Link cable to connect 2280S digital I/O to Trigger Link I/O on other Keithley instruments 4299-8 Single Fixed Rack-Mount Kit 4299-9 Dual Fixed Rack-Mount Kit 4299-10 Dual Fixed Rack-Mount Kit for one 2U Graphical Display Instrument and one Series 26xx Instrument 4299-11 Dual Fixed Rack-Mount Kit for one 2U Graphical Display Instrument and one Series 24xx, Series 2000, or 2U Agilent Instrument KPCI-488LPA IEEE-488.2 Interface Board for the PCI Bus KUSB-488B IEEE-488.2 USB-GPIB Interface Adapter for USB Port with 2m (6.6 ft) cable 7007-05 Double Shielded Premium IEEE-488 Interface Cables, 0.5m (1.6 ft) 7007-1 Double Shielded Premium IEEE-488 Interface Cables, 1m (3.2 ft) 7007-2 Double Shielded Premium IEEE-488 Interface Cables, 2m (6.5 ft) 7007-3 Double Shielded Premium IEEE-488 Interface Cables, 3m (10 ft) 7007-4 Double Shielded Premium IEEE-488 Interface Cables, 4m (13 ft) Precision Measurement, Low Noise, Programmable DC Power Supplies The measurements can be captured using either of two methods. A measurement can be initiated by a digital external control signal transmitted to the external input of the digital I/O port. In addition, up to 2500 measurements can be stored at a sampling rate up to 2800 readings/s based upon a programmed threshold level. The user selects both the level and the slope of the signal, a rising signal or a falling signal. The level setting can be used to store either voltage and/or current measurements when the threshold level is crossed. When the level threshold is enabled, the supply is continuously monitoring the level of the selected parameter and buffering the measurements. Thus pre-threshold measurements can be saved along with the post-threshold measurements. External Triggers start measurements Measurement Complete signals Figure 2. Measure the start-up load currents as a device powers up. View and Control Every Parameter of the Supply for Maximum Performance The bright, 4.3-inch TFT display shows voltage and current readings, the source settings and many additional settings in large, easy-to-read characters. The icon-based main menu provides all the functions users can control and program for fast access to source setup, measurement setup, display formats, trigger options, and system settings. Menus are short, and the menu options you need are easy to find and clearly described, so that you can set up test parameters quickly by using the navigation wheel, keypad, or soft-keys. Many set-up parameters, such as for voltage and current settings, can be entered directly from the home screen; less complex tests don’t even require accessing the main menu to make adjustments. Whether your test’s requirements are uncomplicated or complex, the Series 2280S supplies provide a simple way to set up all the required parameters. Figure 3.

Create and save up to 10 lists of sequenced voltage levels with up to 99 distinct voltages in each list. The duration of each voltage level can be set as short as 1ms or as long as 60s. Create simple linear ramps or any custom configuration from either the front panel or an interface bus. A single trigger will automatically execute the list once or multiple times. Figure 5. Configure the readback measurements exactly the way you need them using a Measure Sub-screen. Controlled Rise and Fall Times Protect Devices Under Test Are you working on a device or a system with a high in-rush current? Series 2280S supplies allow programming the voltage output’s rise time to slow the voltage ramp and avoid voltage overshoot, which could potentially damage the DUT. The voltage fall time can also be controlled to prevent a fast ramp down of the output voltage. Voltage rise and fall times can be set as slow as 10V/s or as fast as 100V/s. Small voltage transitions can be programmed to rise and fall as fast as 1000V/s. Figure 7A. Create an output sequence using the List setup screen.

In addition to displaying a voltage or current waveform or both, they can compute statistics on the stored data. Statistical calculation options include average, maximum, minimum, peak-peak, and standard deviation. All the information you need is accessible through a few display menus. Figure 9. Web page display of the LXI-data logging function showing all parameters stored and the associated statistics. Figure 8. Monitor voltage, current, or both with the graphing function. Simple, Yet Powerful Data Logging As well as capturing 2500 data points in the internal memory and displaying it using the Series 2280S graphing function, voltage and current measurements can be collected using the LAN interface and the Series 2280S built-in web browser. The web interface home page offers a data logging option. Measurements can be taken over a programmed time interval, based on a programmed number of data points, or manually using the Start/Stop button on the webpage user interface. Using the web-based data logger, measurements can be continuously taken over multiple days. Figure 9 shows a web page display of the measurements, the time when measurements were taken, and a number of status parameters. Statistics on the logged data are displayed on the page and include maximum, minimum, and average values. The total consumed electric chage in milliamp-hours is also computed. Control buttons on the side of the display allow control of the data logging and enable copying of either selected rows or all the data. The data can be easily pasted into a report or a spreadsheet for analysis. Just interface to a Series 2280S via LAN and select the data logging option. This powerful data logging capability requires no programming. Automate a test quickly and easily with KickStart software Set up an automated test for the Series 2280S supplies in four simple steps with the KickStart start-up software. KickStart is available for installation on your PC via a free download from www.keithley.com.

Optimized Performance for Production Test Series 2280S supplies are as powerful in a production test system as they are flexible on the R&D benchtop. In addition to their List Mode function, several other Series 2280S features help minimize test time in automated systems. For example, an external trigger input allows hardware synchronization and control by other instruments in the test system. To eliminate many system delays, Series 2280S supplies produce a “measurement ­complete output” to signal the test system when the supplies have ­completed their required actions. To reduce measurement time, the reading speed can be increased by reducing the acquisition time from power line cycle integration times, 16ms at 60Hz (20ms at 50Hz), to 33μs (40μs). Furthermore, the Series 2280S supplies can sink up to 0.45A. Thus, these supplies can quickly discharge a voltage level and change to a different voltage. A choice of front or rear panel terminals provides enhanced connection flexibility. For maximum voltage accuracy, 4-wire remote sensing ensures that the output voltage programmed is actually the level applied to the load. In addition, the sense lines are monitored in order to detect any breaks in them. These features ensure any production problems can be quickly identified and corrected. Four additional digital I/O pins can provide fault status outputs or control an external relay or status lamp. Series 2280S supplies can be controlled via their built-in GPIB, USB, or LAN interfaces. The USB interface is test and measurement system (TMC) compliant. The LXI Core compliant LAN interface supports controlling and monitoring a Series 2280S supply remotely, so test engineers can always access the power supply and view measurements, even if they’re located on a different continent than their test systems.
