Data Sheet
Measurements with the Push of a Button
As the circuits in embedded system designs become more sophisticated,
you must measure a multitude of different parameters to validate your
design. The Tektronix DMM4020 5.5 digit bench multimeter offers a broad
range of functions in one easy-to-use instrument.
Typical multimeter measurements – volts, ohms, and amps – are made with
a basic VDC accuracy of up to 0.015%, ensuring you have the performance
you need for your design. You can also use the DMM4020 to measure
frequency, and to perform continuity and diode tests. This allows you
to replace your counter, continuity tester, and DMM with one versatile
instrument, saving bench space and cost.
Measure Nanoampere Signals
Measuring standby current in today’s energy-efficient designs requires
looking at very low currents, often in the microamp or nanoamp range.
Using a traditional multimeter for this measurement can lead to inaccurate
results since they typically employ the shunt resistance technique for
measuring current.
The DMM4020 offers an improved method for measuring low currents. By
using a current-to-voltage op amp technique, the DMM4020 can make
current measurements with 1 nA of resolution and with minimal loading
affect on the circuit under test, giving results that reflect real-world operation
of the device.
Designed to Make Your Work Easier
The DMM4020 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.

Limit compare mode on the DMM4020.
Setup Buttons for Your Common Measurements
With six setup buttons on the front panel, you can save the settings for your
most common measurements. Simply set up the meter for a measurement,
then press shift followed by a setup button to save the measurement
settings. Now each time you perform that measurement, you simply press
the appropriate setup key.
Dual Display
With the unique dual display, you can measure two different parameters of
the same signal from one test connection.
Limit Compare
The limit compare mode provides pass/fail indicators to quickly show if a
test passes or fails to help eliminate mistakes, especially for results that
are close to the limit.
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.
Easy Connectivity to Your PC
The RS-232 port on the back panel can be used to connect to your PC.
A USB to RS-232 interface adapter cable is included standard with the
DMM4020 for connecting to your PC’s USB port.
