DMM7510

Datasheet DMM7510 7½-Digit Graphical Sampling Multimeter The DMM7510 combines all the advantages of a precision digital multimeter, a graphical touchscreen display, and a high speed, high resolution digitizer to create an industry first: a graphical sampling multimeter. The digitizer gives the DMM7510 unprecedented signal analysis flexibility; the five-inch capacitive touchscreen display makes it easy to observe, interact with, and explore measurements with “pinch and zoom” simplicity. This combination of high performance and high ease of use offers unparalleled insight into your test results. A Tektronix Company Key Features • Precision multimeter with 3½- to 7½-digit resolution • Capture and display waveforms or transients with 1 MS/sec digitizer • Large internal memory buffer; store over 11 million readings in standard mode or 27.5 million in compact mode • 14 PPM basic one-year DCV accuracy • 100 mV, 1 Ω, and 10 µA ranges offer the sensitivity needed for measuring low level signals such as portable device sleep mode currents Capture Waveforms with the Built-in 1 MS/sec Digitizer Capturing and displaying waveforms and transient events just got easier with the DMM7510’s voltage or current digitizing function. The built-in 1 MS/sec, 18-bit digitizer makes it possible to acquire waveforms without the need to use a separate instrument. The digitizing functions employ the same ranges that the DC voltage and current functions use to deliver exceptional dynamic measurement range. In addition, the voltage digitizing function uses the same DC voltage input impedance (10 GΩ or 10 MΩ) levels to reduce loading significantly on the DUT. • Make accurate low resistance measurements with offset compensated ohms, four-wire, and dry circuit functions • Auto-calibration feature improves accuracy and stability by minimizing temperature and time drift • Display more with five-inch, high resolution touchscreen interface • Readings and screen images can be saved quickly via the front panel USB memory port • Multiple connectivity options: GPIB, USB, and LXIcompliant LAN interfaces • Two-year specifications enable longer calibration cycles The built-in graphing utility supports displaying and comparing measurements or waveforms from up to four reading buffers at once. Advanced triggering options make it possible to capture a signal at precisely the right point. Datasheet Determine the current drain of the components such as the microcontroller (MCU) in your lowpower, battery-operated product as well as the product’s total current draw. In addition, profile the current drain in all of the product’s operating states from its sleep mode to its transmit mode. Using the enhanced accuracy DC current function, the DMM7510 can measure a 1 µA sleep mode current with 1 pA resolution and with 0.375 nA tolerance. Furthermore, using the digitizing current function, the DMM7510 can capture the current wave shapes as the product transitions from sleep mode to transmit mode. Make Demanding Measurements with Confidence The DMM7510’s design makes the most of Keithley’s low level measurement expertise. Features like the low noise input stage and the 32-bit A-to-D converter allow this instrument to deliver DC accuracies typically only found in metrologygrade instrumentation—but at about half the price of those solutions. The DMM7510’s 100 mV, 10 Ω, and 10 µA ranges deliver the sensitivity needed to measure low signals with confidence when characterizing today’s demanding electronic designs. In addition to one- and two-year accuracy specifications, an auto-calibration function ensures greater accuracy between calibration cycles. One Power Line Cycle Noise Performance The DMM7510 provides noise performance equivalent to or better than many 8½-digit DMMs. 2µV 1µV Volts Accurately Measure and Visualize Ultra-Low Current Drain Levels 0µV –1µV –2µV 6½ Digit 8½ Digit DMM7510 Comparison of the DMM7510’s 1 VDC noise performance with that of typical 6½- and 8½-digit multimeters. All data was taken at 1 NPLC with a low thermal short applied to the input. Capture the current drain from all the operating states – sleep mode to active transmit mode – of a component or a product with the DMM7510’s digitizing function. Focus in on characteristics of the wave shapes with the touchscreen pinch and zoom features. 15 Measurement Functions The DMM7510 provides 15 basic measurement functions. In addition to the digitizing voltage and current functions, it includes capacitance, ACV and ACI, temperature (RTD, thermistor, and thermocouple), 2- and 4-wire resistance, dry circuit ohms, period, frequency, diode test, and DC voltage ratio. The instrument’s flat menu structure allows for fast configuration and improves usability. Its intuitive design lets you to learn how to operate the instrument and begin making device measurements faster and with greater confidence.

The embedded scripting capability allows running powerful test scripts directly on the instrument, without the need for an external PC controller. These test scripts are complete test programs based on an easy-to-use yet highly efficient and compact scripting language, Lua (www.lua.org). Scripts are a collection of instrument control commands and/or program statements. Program statements control script execution and provide facilities such as variables, f­unctions, branching, and loop control. This allows you to create powerful measurement applications with significantly reduced development times. Test scripts can contain any sequence of routines that are executable by conventional programming languages (including decision-making algorithms), so the instrument can manage every facet of the test without the need to communicate with a PC for decisionmaking. This eliminates delays due to GPIB, Ethernet or USB traffic congestion and greatly improves overall test times. TSP technology also offers “mainframe-less channel expansion.” The TSP-Link® channel expansion bus and a 100 Base T Ethernet cable allow connecting multiple DMM7510s with other TSP-enabled instruments in a master-slave configuration so they operate as a single integrated system. These instruments include the 2450 and 2460 Graphical SourceMeter® SMU instruments, Series 2600B 4 TEK.COM SourceMeter SMU instruments, and the Series 3700A Switch/Multimeter systems. TSP-Link supports up to 32 units per GPIB or IP address, so it’s easy to scale a system to fit the requirements of an a ­ pplication. A standard SCPI programming mode supports taking advantage of all of the DMM7510’s new features when programming remotely. In addition, the instrument is code-compatible with the SCPI language, which many other DMMs use. This code compatibility avoids the need to rewrite code that is normally associated with upgrading to a new instrument with new ­capabilities.
