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.

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

Limit compare mode on the DMM4020.
 

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.

Measurement Method

AC-coupled input using the AC voltage measurement function

Settling Considerations

When measuring frequency after a DC offset voltage change, errors may occur. For the most accurate measurement, wait up to 1 second to allow input-blocking RC time constant to settle

Measurement Considerations

To minimize measurement errors, shield inputs from external noise when measuring low-voltage, low-frequency signals
