Feature-Rich Tools for Precision Measurements

As the circuits in embedded system designs become more sophisticated with tighter tolerances, you must measure a multitude of different parameters with a high degree of accuracy to validate your design. The Tektronix DMM4050 and DMM4040 6.5 digit bench multimeters pack many different functions and analysis into one instrument, all with exceptional precision and performance.

Typical multimeter measurements – volts, ohms, and amps – are made with a basic VDC accuracy of up to 0.0024%, and resolution of 100 pA and 10 µ?, ensuring you have the performance you need for today’s demanding designs. You can also use the DMM4050/4040 to measure frequency and period, and to perform continuity and diode tests. For additional flexibility, the DMM4050 offers temperature and capacitance measurements. This allows you to replace your temperature meter, capacitance meter, counter, continuity tester, and traditional DMM with one versatile instrument, saving bench space and cost.

Analyze Your Device with Graphical Display Modes

With the unique dual display of the DMM4050/4040, you can measure two different parameters of the same signal from one test connection. To reveal signal quality issues like drift, intermittent transients, and stability, you can view the data as a real-time trend plot or a histogram with the DMM4050/4040’s graphical display mode, or you can use measurement statistics to track how signal parameters are changing over time.

TrendPlot™ Paperless Recorder Mode
Depending on your test case, your signal parameters may change from instant to instant. By taking multiple measurements over minutes, hours, or days, you can quantify those changes. With TrendPlot™, you can graphically plot the trend of a measured value over time, from short time spans to extended periods of time. TrendPlot can be used with measurements like DC voltage, DC current, frequency, resistance, and temperature. AC voltage and current can be plotted as RMS measurements.

Measurement Statistics
With integrated statistics processing, you can calculate both the average and standard deviation of a measurement, as well as track the minimum and maximum measured values, with the push of a button. Statistics can be performed on DC voltage, AC voltage, AC voltage in dB, DC current, AC current, resistance, capacitance, frequency, period, and temperature measurements.

Histogram Plots
To graphically see the average and standard deviation of a set of measurements, you can use the histogram function to see the distribution of measurement results.

Designed to Make Your Work Easier

The DMM4050/4040 multimeter is designed with the ease of use and familiar operation you expect from Tektronix.

Intuitive Operation

Dedicated front-panel buttons provide fast access to frequently used functions and parameters, reducing setup time. You no longer need to search through software menus to find the function you need.

Dual Display

With the unique dual display, you can measure two different parameters of the same signal from one test connection

Easy Data Storage and PC Connectivity

A USB port on the front panel makes it easy to store measurement data and instrument setups to a memory stick. Or connect to your PC with the LAN, RS-232, or GPIB port on the back panel. A USB to RS-232 interface adapter cable is included standard with the DMM4050/4040 to make it easy to connect to your PC’s USB port.

Simple and Accurate 4-wire Measurements

Patented split terminal jacks for the 2×4 ohms function allow you to perform 4-wire measurements using only two leads instead of four. Special test lead accessories are available to enable you to establish the connection. You get excellent resolution and accuracy plus the convenience and ease of using a single pair of leads.

Connect Your Bench for Intelligent Debug

Easily capture, save, and analyze measurement results from your multimeter with the special Tektronix Edition of National Instrument’s LabVIEW SignalExpress™ software. Every DMM4050 and DMM4040 ships with a free copy of the Limited Edition version of SignalExpress for basic instrument control, data logging, and analysis. The optional Professional Edition offers over 200 built-in functions that provide additional signal processing, advanced analysis, sweeping, limit testing, and user-defined step capabilities.

SignalExpress supports the range of Tektronix bench instruments^*1, enabling you to connect your entire test bench. You can then access the feature-rich tools packed into each instrument from one intuitive software interface. This allows you to automate complex measurements requiring multiple instruments, log data for an extended period of time, time correlate data from multiple instruments, and easily capture and analyze your results, all from your PC. Only Tektronix offers a connected test bench of intelligent instruments to simplify and speed debug of your complex design.

Performance You Can Count On

In addition to industry-leading service and support, every DMM4050 and DMM4040 multimeter comes backed with a three-year standard warranty.
