Keithley Instruments announced today the introduction of the DMM7510 7½-digit graphical sampling multimeter, which the company calls the first of a new class of digital multimeters. It integrates a high accuracy digital multimeter, a digitizer for waveform capture, and a capacitive touchscreen user interface. The DMM7510 is designed to give users confidence in the accuracy of their results, the ability to explore measurements further, and intuitive touchscreen operation. Its user interface continues the company’s “Touch, Test, Invent” design philosophy that lets users learn faster, work smarter and invent easier.
Jerry Janesch, a senior market development manager at Keithley, noted, “To get an in-depth understanding of their devices under test, engineers need to capture small signals at higher accuracy and faster speeds than traditional DMMs can provide. The DMM7510’s intuitive operation and high-speed digitizer allow it to address a wide range of test applications, including device characterization, debugging, and analysis; production test/ATE; and applications in research labs and universities.”
The DMM7510 offers users a combination of capabilities, including high measurement accuracy, so they can be confident of the integrity of their results. The precision multimeter offers the flexibility to select resolution levels from 3½ to 7½ digits, and it provides 14-ppm basic 1-year DCV accuracy, typically only found in metrology-grade instrumentation—but at about half the price of those solutions.
In addition, expanded measurement ranges (100 mV, 1Ω, and 10 µA) enhance low-level accuracy, and an auto-calibration feature minimizes temperature and time drift. Low burden voltage improves low current measurement accuracy.
The instrument features high accuracy signal sampling with a 1 MS/s, 18-bit digitizer, and users can view and analyze current and voltage waveforms and transients without the need for an additional instrument or PC. Enhanced analog triggering includes edge, pulse, and window triggers, and the instrument is suitable for low-level power analysis, sensor test, medical device R&D, and component test.
The five-inch capacitive touchscreen interface/display supports setting up tests faster and more intuitively, and viewing results both numerically and graphically, and the touchscreen interface allows users to interact with the signals they’re studying for greater insights into results. Pan, pinch, and zoom functions and the ability to set cursors support flexible signal capture and allow for high interaction with test data.
Test results stored in any of the data buffers can be displayed in graph, histogram, or numerical/datasheet form. A built-in graphing utility supports displaying and comparing measurements or waveforms from up to four reading buffers at once. Test results and screen images can be stored quickly via the USB 2.0 memory port.
Built-in support is provided for low resistance applications, including dry circuit, offset compensation, and open lead detection. A rotary control knob offers an alternative to touchscreen navigation. Front/rear input selector indicates the inputs currently in use.
Connections and controls simplify configuring multi-instrument test solutions, including input connectors, remote control interfaces (GPIB, USB 2.0, and LXI/Ethernet), a D-sub 9-pin digital I/O port (for internal/external trigger signals and handler control), and TSP Link jacks for connecting to other Keithley instruments with an embedded Test Script Processor (TSP). Free KickStart instrument control start-up software lets PC users configure and take measurements quickly.
The U.S. list price for the DMM7510 is $3,990.
