Feature-Rich Tools for Precision
Measurements
As the circu
its in emb edded system designs become mo re sophisticated
with tighter tolerances, you mu st measure a multitude of different
parameters with a high degre e of a c curacy to validate your design. The
Tektronix DMM4050 and DMM404 0 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 a nd 10
,ensuri
ng you have the performance you need for today’s demanding
designs. You can also use the DMM4050/4040 to measure frequency and
period, and t o perform continuity and diode tests. For additional flexibility,
the DMM4050 offers temperature and capacitance measurements. This
allows you to r eplace your temperature meter, capacitance meter, counter,
continuity tester, and traditional DMM with one versatile instrument, saving
bench spac
e and cost.
Analyze Your Device with Graphical Display
Modes
With the unique dual display of the DMM4050/4040, yo u 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 ca n 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
statisti
cs to track h ow signa l pa ramete rs 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 me asurements over minutes,
hours, or days, you can quantify those changes. With TrendPlot™,
you can g
raphically plot the trend of a mea sured va lu e over time, from
short time spans to extend ed periods of time. TrendPlot can be used
with mea surements like DC v oltage, DC current, frequency, resist ance,
and temperature. AC voltage and current can be plotted as RMS
measurements.

nt Statistics
With integrate d statistics processing, you can calculate both the average
and standa
rd deviation of a mea surement, as well as track the minimum
and maximum measured values, with the push of a button. Statistics can
be perfo rmed 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 t he average an d standard deviation of a se t 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.
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 con nect 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 DMM4050/404 0 to make it easy
to conn ect to your PC’s USB port.
Simple and Accurate 4-wire Measurements
Patent
ed sp lit 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 e s tablish the connection. You get
excellent resolution and accuracy plus the conve nience and ease of using a
single pair of leads.
