Today’s oscilloscopes have far more functionality than their old cathode-ray tube (CRT) analog counterparts. At first glance, the proliferation of all of those knobs and buttons may seem overwhelming, ...

Many common problems can be solved easily using the edge trigger of an oscilloscope. But sometimes a more complicated trigger mode such as pulse triggering can shorten the troubleshooting cycle. This ...

In designing and testing an embedded system, engineers need to provide a way for the various devices and subsystems on the system, such as DACs, low-speed ADCs, fan control chips, EEPROMs, and PLDs to ...

When looking at protocol information on a bus, an oscilloscope may not be the first instrument to come to mind�until now. As most engineers know, digital oscilloscopes are an indispensable ...

As technology advances, finding the culprit in a malfunctioning device has become somewhat more difficult. As an example, troubleshooting an AM radio is pretty straightforward. There are two basic ...

Modern embedded system designs present challenges for EMI testing and troubleshooting that didn’t exist years ago. These challenges include switching power supplies, high speed system clocks and data ...

In my recent technology report "The Ultimate Test Drive: High-Octane Oscilloscopes" , I got a chance to write about digital sampling oscilloscopes (DSOs). These instruments are truly amazing today ...

There was a time when every broadcast engineer had an oscilloscope for troubleshooting and aligning equipment, from a microphone input to the antenna. It is true that the nature of our plug-and-play ...

Anyone who has tried to troubleshoot an interference problem knows it can be a lot like chasing ghosts. Just about the time you think you have it, all trace of it disappears or, worse yet, the ...
