Feature-Rich Tools for PrecisionMeasurementsAs the circuits in embedded system designs become more sophisticatedwith tighter tolerances, you must measure a multitude of differentparameters with a high degree of accuracy to validate your design. TheTektronix DMM4050 and DMM4040 6.5 digit bench multimeters pack manydifferent functions and analysis into one instrument, all with exceptionalprecision and performance.Typical multimeter measurements – volts, ohms, and amps – are made witha basic VDC accuracy of up to 0.0024%, and resolution of 100 pA and 10μΩ, ensuring you have the performance you need for today’s demandingdesigns. You can also use the DMM4050/4040 to measure frequency andperiod, and to perform continuity and diode tests. For additional flexibility,the DMM4050 offers temperature and capacitance measurements. Thisallows you to replace your temperature meter, capacitance meter, counter,continuity tester, and traditional DMM with one versatile instrument, savingbench space and cost.
Analyze Your Device with Graphical DisplayModesWith the unique dual display of the DMM4050/4040, you can measuretwo different parameters of the same signal from one test connection. Toreveal signal quality issues like drift, intermittent transients, and stability,you can view the data as a real-time trend plot or a histogram with theDMM4050/4040’s graphical display mode, or you can use measurementstatistics to track how signal parameters are changing over time.
TrendPlot™ Paperless Recorder ModeDepending on your test case, your signal parameters may changefrom 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, fromshort time spans to extended periods of time. TrendPlot can be usedwith measurements like DC voltage, DC current, frequency, resistance,and temperature. AC voltage and current can be plotted as RMSmeasurements.

Histogram display.
Measurement StatisticsWith integrated statistics processing, you can calculate both the averageand standard deviation of a measurement, as well as track the minimumand maximum measured values, with the push of a button. Statistics canbe performed on DC voltage, AC voltage, AC voltage in dB, DC current,AC current, resistance, capacitance, frequency, period, and temperaturemeasurements.
Histogram PlotsTo graphically see the average and standard deviation of a set ofmeasurements, you can use the histogram function to see the distribution ofmeasurement results.
Designed to Make YourWork EasierThe DMM4050/4040 multimeter is designed with the ease of use andfamiliar operation you expect from Tektronix.
Intuitive OperationDedicated front-panel buttons provide fast access to frequently usedfunctions and parameters, reducing setup time. You no longer need tosearch through software menus to find the function you need.
Easy Data Storage and PC ConnectivityA USB port on the front panel makes it easy to store measurement dataand instrument setups to a memory stick. Or connect to your PC with theLAN, RS-232, or GPIB port on the back panel. A USB to RS-232 interfaceadapter cable is included standard with the DMM4050/4040 to make it easyto connect to your PC’s USB port.
Simple and Accurate 4-wire MeasurementsPatented split terminal jacks for the 2×4 ohms function allow you to perform4-wire measurements using only two leads instead of four. Special test leadaccessories are available to enable you to establish the connection. You getexcellent resolution and accuracy plus the convenience and ease of using asingle pair of leads.

Flexible counting technique. AC-coupled input usingthe AC voltage measurement function
SettlingConsiderations
When measuring frequency or period after a DCoffset voltage change, errors may occur. For themost accurate measurement, wait up to 1 second forthe input blocking capacitor to settle
MeasurementConsiderations
To minimize measurement errors, shield inputsfrom external noise when measuring low-voltage,low-frequency signals
