No Programming Required:
Digitizing Signals and
Analyzing Data with a DMM
Application Note
Introduction
Keysight Technologies, Inc. digital multimeters are ubiquitous on work benches and in automated
test systems. You have most likely used one at some point in time. They measure basic electrical
properties and give you a clear reading. More sophisticated DMMs have higher precision, data
logging capability, and higher measurement speeds. If your DMM has these capabilities, you can
use it to digitize your signals. Digitizing is useful to understand your signal better, and you can plot
the data for a visual representation of your signal. Digitizing with your DMM has been simpliied with
the Keysight DMM Connectivity Utility.
This measurement brief explains how the new Keysight DMM app can help you digitize your signals
and understand your data faster. In a couple of clicks, it can graph your measurements. The app also
synchronizes multiple DMMs and allows you to put together a multichannel DMM system.
Snapshot
A mechanical engineering student was designing an airplane wing for his luid dynamics class. In order
to evaluate the lex of the wing under different conditions, he needed to be able to measure forces on
the wing in at least four different locations. He had some force transducers that change resistance
depending on strain, these sensors were as old as he is. Since he is an undergrad, he did not have
access to the really expensive equipment that the Graduate students use. He realized that he had
access to the electronics' lab equipment to borrow a few DMMs. The student downloaded the Keysight
DMM Connectivity Utility and used the app to setup his measurement. He was going to take lot of
discrete data points then put the data together in Excel later. But he found out that he can use this
app to digitize all four points and graph the data right away. In an afternoon, he's able to digitize the
tranducer outputs in parallel and sweep through all of the test conditions. He then spent the rest of the
weekend "studying".
