TekMark Australia distributes the Tektronix brand of test and measurement as well as monitoring tools in Australia.
Tektronix, Inc., the world's leading manufacturer of oscilloscopes announced results from the Time and Motion Study conducted by research firm Hansa|GCR titled, “Finding Runts and Glitches in Digital Signals: An Examination of User Experience with Three Oscilloscopes,” that was conducted in December 2009.
The study concluded that the Tektronix MSO4000 Mixed Signal Oscilloscope was preferred by over two-thirds of the participants and was 53 percent faster in finding runts and glitches when debugging a design.
Timing errors and physical layer issues plague every new digital design, causing engineers to lose countless hours trying to find and troubleshoot these problems.
The Time and Motion Study examined user experiences when performing common test tasks involved in debugging these issues, such as finding and analysing runts and glitches, using three comparable oscilloscopes from Tektronix, Agilent and LeCroy in the $20,000 price range.
“For this study we conducted in-person interviews with 47 experienced oscilloscope users, asked them to complete the same debug task from start to finish and to describe their experience,” said Andrea Eaker, Senior Research Consultant, Hansa|GCR.
“This directional research indicated that users were able to find runts and glitches in a signal twice as fast with the Tektronix oscilloscope compared to the Agilent and LeCroy scopes. Users also found the automated search feature and available triggers particularly useful in completing these tasks, and Tektronix received the highest satisfaction ratings overall.”
The expert oscilloscope user participants were asked to perform three tasks on each scope:
- Set up the oscilloscope to monitor for glitches and runts
- Set up a trigger and capture a runt
- Search the waveform to locate all runt instances
As the research study indicates, all participants were given a two-minute time limit to complete each task.
The Tektronix oscilloscope was the only instrument that participants were able to complete all the three tasks with, well under the two-minute time limit.
Participants did not experience similar success with the other two instruments. With both the LeCroy and Agilent oscilloscopes, several of the experienced participants failed to complete 2 out of the 3 test tasks within the allotted time.
“The Hansa|GCR research study confirms what oscilloscope users have known for over 60 years. Tektronix scopes offer a comprehensive set of easy-to-understand-and-operate tools for every stage of debug,” said Roy Siegel, General Manager, Mid-range Oscilloscopes, Tektronix.
“Our oscilloscopes enable engineers to discover and capture problems in their design, then search and analyse those problems to find root cause – fast. This in turn leads to greater productivity and faster time to market.”
