The DMM7510 7½-Digit Graphical Sampling Multimeter integrates a high-accuracy digital multimeter, a digitizer for waveform capture, and a capacitive touchscreen user interface. The instrument is a precision multimeter with selectable resolution levels from 3½ to 7½ digits and provides DC accuracies typically only found in metrology-grade instrumentation. It has a 14 ppm basic 1-year DCV accuracy and expanded measurement ranges (100 mV, 1 Ω, and 10 μA) for low-level accuracy. An auto-calibration feature minimizes temperature and time drift and signal sampling utilizes a 1 MS/sec, 18-bit digitizer. Instrument users can view and analyze current and voltage waveforms and transients without the need for an additional instrument or PC.
The DMM includes enhanced analog triggering modes for edge, pulse, and window triggers. Users can employ the five-inch capacitive touchscreen interface for setting up tests and viewing results both numerically and graphically. The touchscreen interface lets users 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 display in graph, histogram, or numerical/datasheet form. A built-in graphing utility supports display and comparison of measurements or waveforms from up to four reading buffers simultaneously. A USB 2.0 memory port facilitates storage of test results.
The instrument includes support for low-resistance applications, including dry circuit, offset compensation, and open lead detection. A rotary control knob offers an alternative to touchscreen navigation.
Control interfaces consist of 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.
The US list price for the DMM7510 is $3,990. More information on the DMM7510 is available on Keithley’s website at www.keithley.com/dmm7510.
