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
,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 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.

Histogram display.
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.
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.

Measurement
Method
Flexible counting technique. AC-coupled input using
the AC voltage measurement function

Considerations
When measuring frequency or period after a DC
offset voltage change, errors may occur. For the
most accurate measurement, wait up to 1 second for
the input blocking capacitor to settle
Measurement
Considerations
To minimize measurement errors, shield inputs
from external noise when measuring low-voltage,
